Update.
2003-04-01  Ulrich Drepper  <drepper@redhat.com>

	* pthread_create.c (deallocate_tsd): Clear/free memory after the last
	round, not the first.  Use specific_used flag instead of local
	found_nonzero variable.  Use THREAD_[SG]ETMEM where possible.
	(__free_tcb): Don't call deallocate_tsd here.
	(start_thread): Call deallocate_tsd here.
	* pthread_setspecific.c: Set specific_used flag really only when
	needed.
	* Makefile (tests): Add tst-tsd3.c
	* tst-tsd3.c: New file.
