  26         MEMORY_BARRIER.

  56         to dynamically detect RT signals and avoid generating compatibility
  57         functions with old kernel.
  58         * restart.h (restart) [__ASSUME_REALTIME_SIGNALS]: Use
  59         __pthread_restart_new directly.

  80         the code.

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