Comment:

 No, at_thread_exit should not work on the main thread.

 If you call exit() then all threads are abruptly terminated without
 calling their exit handlers.

 Returning from main is defined to be equivalent to calling exit(), so all
 threads (including the main thread) are terminated without calling exit
 handlers.

 On POSIX, if you exit the main thread by calling pthread_exit() then the
 thread exit handlers should run. Similarly, on Windows you can use
 ExitThread(). However, I would recommend using atexit or explicit calls,
 or even just normal destructors, since using pthread_exit() or ExitThread
 will not run destructors for automatic_objects.
