Update.
Jakub Jelinek <jakub@redhat.com> * nscd/Makefile (nscd-modules): Add nscd_setup_thread. * nscd/connections.c (nscd_run): Call setup_thread for maintenance threads. * nscd/nscd-client.h (struct database_pers_head): Add nscd_certainly_running field. * nscd/nscd.h: Declare setup_thread. * nscd/nscd_helper.c (__nscd_get_map_ref): Avoid the time test if nscd_certainly_running is nonzero. 2004-09-08 Ulrich Drepper <drepper@redhat.com>
