[PATCH] Avoid pthread_exit in librt.so.1

[Jakub Jelinek <jakub at redhat dot com>]

Hi!

Its a little hard to preach how costly pthread_exit (NULL); at the very end
of a thread main routine is compared to return NULL when glibc itself uses
it too...

2004-08-11  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/pthread/aio_misc.c (handle_fildes_io): Remove noreturn
	attribute.  Return NULL instead of calling pthread_exit at the end.
