Bugfix to pthread_key_delete. It was iterating over the thread

* sysdeps/ia64/pspinlock.c (__pthread_spin_lock): Add

exchange operation (cmpxchg4). This avoids the spinning on the

inuse flag, because this requires mutex to be held. Callers updated
to do the check when they have the mutex.
* sysdeps/pthread/timer_getoverr.c: Add check for inuse here.
* sysdeps/pthread/timer_settime.c (timer_settime): Tighter critical
regions: avoids making system calls while holding timer mutex, and
a few computations were moved outside of the mutex as well.
* sysdeps/pthread/timer_gettime.c (timer_gettime): Likewise.
* sysdeps/pthread/posix-timer.h (list_unlink_ip): Function name changed
to list_unlink_ip, meaning idempotent. Pointer manipulation
changed to get better better code out of gcc.
* sysdeps/pthread/timer_routines.c (list_unlink): Non-idempotent
version of list_unlink added here.
* sysdeps/pthread/timer_delete.c: Use appropriate list unlink
function in all places: idempotent one for timers, non-idempotent

which lock and unlock the stream list using the new interface
provied by libio.

2000-05-12 Kaz Kylheku <kaz@ashi.footprints.net>
Bugfix: The pthread_atfork mechanism now takes care of its
own internal mutex at fork time.
* ptfork.c (__fork): Revised so that the mutex is held across
the fork operation and while the handlers are called, and so that
the child resets the mutex.
* linuxthreads.texi: Updated pthread_atfork documentation to make
it clear that fork and pthread_atfork can't be reentered from
atfork handlers, that pthread_atfork and fork are mutually atomic,
and that the handlers are inherited by the child process.

* mutex.c (pthread_once): IN_PROGRESS state of pthread_once_t
object state is represented with additional bits which distinguish
whether that state was set up in the current process, or
in an ancestor process. If that state was set in an ancestor,
it means that a fork happened while thread was executing the init
function. In that case, the state is reset to NEVER.

unblocking main thread.
* manager.c (__pthread_manager_sighandler): If the main thread
is waiting for all other threads to die, send a REQ_KICK into
the thread manager request pipe to get it to clean out the threads
and unblock the main thread as soon as possible. This fixes
the 2000 millisecond hang on shutdown bug.

including the main one call pthread_exit(), or implicitly do so.

if fast mutex is used. Don't initialize `already_canceled' twice.

Redesigned how cancellation unblocks a thread from internal
cancellation points (sem_wait, pthread_join,
pthread_cond_{wait,timedwait}).
Cancellation won't eat a signal in any of these functions
(*required* by POSIX and Single Unix Spec!).
* condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
simultaneous condition variable signal (not required by POSIX
or Single Unix Spec, but nice).
* spinlock.c: __pthread_lock queues back any received restarts
that don't belong to it instead of assuming ownership of lock
upon any restart; fastlock can no longer be acquired by two threads
simultaneously.
* restart.h: Restarts queue even on kernels that don't have
queued real time signals (2.0, early 2.1), thanks to atomic counter,
avoiding a rare race condition in pthread_cond_timedwait.
