Update.

1998-05-04 12:40  Ulrich Drepper  <drepper@cygnus.com>

	* malloc/malloc.c (ptmalloc_init_all): New function.  Similar to
	ptmalloc_unlock_all, but re-initializes the mutexes instead.
	(ptmalloc_init): Use new function in thread_at_fork call.
	(thread_atfork_static): Likewise.
	Suggested by Wolfram Gloger and Xavier Leroy.
