    Returning from the thread does not call exit. Only returning from "main" 
does, and this is true for any thread. Essentially, the code looks like 
this:

init();
main();
exit();

    So there's nothing special about the thread, just that if you return 
from 'main', the thread will call 'exit'. If your platform has a tricky way 
for you to get another thread to return from 'main' (say by saving the 
context and resuming it with another thread), try it, and you'll find that 
the process exits just the same.
