24 before every nanosleep call to account for time spent in the rest

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

138 new_thread_bottom. Correct handling of stack size and when the
139 rlimit method to guard for stack growth is used.
140 * pthread.c (pthread_initialize): Stack limit must be STACK_SIZE
141 minus one pagesize (not two).
143 1999-12-03 Andreas Jaeger <aj@suse.de>
145 * Versions: Add __res_state with version GLIBC_2.2.
