According to Anoop on 6/6/2008 4:48 AM:
| Being more specific, if a thread is registering a handler using atexit()
| while
| exit() is processing the already registered handlers in the main thread,
| what is the expected behavior as per the standard?

The standard is clear (and requires the same as C99): "At normal program
termination, all functions registered by the atexit() function shall be
called, in the reverse order of their registration, except that a function
is called after any previously registered functions that had already been
called at the time it was registered."

So if an additional atexit() function is registered during exit()
processing, that newly-registered handler will be the next handler
executed when the current handler completes.
