119 Redesigned how cancellation unblocks a thread from internal
120 cancellation points (sem_wait, pthread_join,
121 pthread_cond_{wait,timedwait}).
122 Cancellation won't eat a signal in any of these functions
123 (*required* by POSIX and Single Unix Spec!).
124 * condvar.c: Spontaneous wakeup on pthread_cond_timedwait won't eat a
125 simultaneous condition variable signal (not required by POSIX
126 or Single Unix Spec, but nice).
127 * spinlock.c: __pthread_lock queues back any received restarts
128 that don't belong to it instead of assuming ownership of lock
129 upon any restart; fastlock can no longer be acquired by two threads
131 * restart.h: Restarts queue even on kernels that don't have
132 queued real time signals (2.0, early 2.1), thanks to atomic counter,

178 new_thread_bottom. Correct handling of stack size and when the
179 rlimit method to guard for stack growth is used.
180 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
181 minus one pagesize (not two).
183 1999-12-03 Andreas Jaeger <aj@suse.de>
185 * Versions: Add __res_state with version GLIBC_2.2.
