129 Redesigned how cancellation unblocks a thread from internal
130 cancellation points (sem_wait, pthread_join,
131 pthread_cond_{wait,timedwait}).
132 Cancellation won't eat a signal in any of these functions
133 (*required* by POSIX and Single Unix Spec!).
134 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
135 simultaneous condition variable signal (not required by POSIX

138 that don't belong to it instead of assuming ownership of lock
139 upon any restart; fastlock can no longer be acquired by two threads

188 new_thread_bottom. Correct handling of stack size and when the
189 rlimit method to guard for stack growth is used.
190 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
191 minus one pagesize (not two).
