The requisite caveats, before commenting: I don't qualify for the 'chucked it all' credential (at least I don't think I do). But, I definitely qualify for the academic piece (26 years as tenured faculty), so I may be able to comment on the future employment question. I also have an expat brother-in-law who has spent most of his adult life teaching ESL outside the US (in Libya, China, UAE, Korea, etc.) and has never had a moment's regret for doing it - his needs are simple and his life is interesting and exciting.

Are there academics who ... chucked it all and became OW instructors? ... I'll finish my Masters degree in Library Science in a month ... Since returning to the States last August, all of my thoughts have been that I want back out. The expat life really grabs you, I think.
Such would be the assessment of my brother-in-law as well. Personally, I suspect it is as much the travel bug as the expat life, though. But, that may just be what I like.

Then again, if I wanted to get into my profession 10 years from now, how are employers going to look at the idea that I abandoned my profession right after getting the degree and went off on what some might consider "a wandering lark"?
I had a graduate student who, after finishing her Master's, decided to go live in Colorado for two years, skiing. She returned to an excellent position in a non-profit foundation, and the people who hired her were positively swayed by her independence and self-direction, for taking the time off. I don't hear you saying you really want to abandon your training and work, just approach it in a different way. Any 'employer' who would view that course negatively is someone for whom you do not want to work, anyway. There are always plenty of jobs for good people - intelligent, energetic, mentally agile. And, good people often find that their career leads them, rather than the other way around. Who knows where you will end up? But, enjoy the ride, particularly if it involves diving.
Of course, to 'chuck it all' is not necessarily a bad thing for some. I had a friend many years ago who, after completing his graduate work in psychology, did chuck it all. Went west and became a ski instructor. Then took a vacation in the tropics, fell in love with diving, moved there, became an instructor and is still (happily) there several decades later. There are worse things in the world than waking up in a warm, sunny place, and getting in the water each day.

My idea is that I want to pursue a career in International Librarianship. I want to build services in places that don't have them, and I want to be able to help people reach information.
Then move to a place where you can dive, where you can even teach diving, perhaps, AND where you can become involved in doing just what you say you want to do - 'I want to build services in places that don't have them'. Even if you do it as a volunteer to begin with, the credential you add to your resume is invaluable! I far prefer to hire people who have tasted life than people who have great academic credentials and no zest for living. In fact, one of my standard interview questions for prospective project manager hires is, 'What do you do outside of work for fun?' If they say, 'I like to be with friends.' I am somewhat less enthused than if they say, 'I play with a woman's lacrosse club in the evnings and weekends after work.', or 'I like to jump out of airplanes.'

While working in a public library or established academic library would be nice, I just don't know if that's what I want to do now. ...
Actually, 'BORING' is a term that also comes to mind. And that has nothing to do with your discipline. I left academia after a long stay because I was terminally bored. I was succesful, rather well-paid by academic standards, particularly compared to the arts and sciences faculty, but bored to tears (except for the teaching, which I loved). So, I ended up in an enviroment where I use my original professional training, and have both the time flexibility to dive and the income to support it. There is no magic formula.

Am I crazy for thinking that I'm only young once, so if I want to move to Thailand and get my OWSI and then work as an OWSI, maybe do ESL on the side and at the same time do some volunteer work in my field, I should do it?
I cannot speak for OWSI and ESL work in Thailand. But, you ARE only young once. (If you are of the right mindset, you are also always young, but still only once. )
On the 'Banana Wind' CD, Jimmy Buffet includes what he calls a hidden track. One of the lines from the refrain to that track may have relevance to your plans - 'I don't do bidness that don't make me smile!' Go diving, see the world, experience lots of people and places (and dive sites). A career will find you.
