+       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.
