+
+ 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.
