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.
