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

146 new_thread_bottom. Correct handling of stack size and when the
147 rlimit method to guard for stack growth is used.
148 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
149 minus one pagesize (not two).
151 1999-12-03 Andreas Jaeger <aj@suse.de>
