If you call exit() then thread exit handlers are not called. "return 0"
in main() is the same as calling exit(0), so thread exit handlers are
not called.

No.

If you call pthread_exit(0) from main() then thread exit handlers *will*
be called. Of course, this doesn't exit the program until all other
threads have terminated, whereas "return 0" kills the other threads.
