Update.
2000-06-10 Kaz Kylheku <kaz@ashi.footprints.net> * sysdeps/pthread/timer_create.c: Thread matching now done on clock type as well as thread attributes. There are individual global signal-delivering threads for different clock types. * sysdeps/pthread/posix-timer.h: Likewise. * sysdeps/pthread/timer_routines.c: Likewise. * sysdeps/pthread/timer_routines.c: Thread allocation and deallocation function now remembers to put thread on active list and remove from active list. Thus now the feature of binding multiple timers to a single thread actually works.
