The compatibility hooks allows you to use libraries and binaries built and linked to libpthread before libc was built with symbol versioning.

| | | | | | | | | | | | | | | | | | | | o Don't reinitialise the atfork() handler list in the child. We are meant to call the child handler, and on subsequent fork()s should call all three functions as normal. o Don't reinitialise the thread specific keyed data in the child after a fork. Applications may require this for context. o Reinitialise curthread->tlflags after removing ourselves from (and reinitialising) the various internal thread lists. o Reinitialise __malloc_lock in the child after fork() (to balance our explicitly taking the lock prior to the fork()). With these changes, it is possible to enable the NOTYET code in thr_kern.c to allow the use of non-async-safe functions after fork()ing from a threaded program.

| | | | | | | | | | | | | | | | | | | | | | | | | signals instead of having more intricate knowledge of thread state within signal handling. Simplify signal code because of above (by David Xu). Use macros for libpthread usage of pthread_cleanup_push() and pthread_cleanup_pop(). This removes some instances of malloc() and free() from the semaphore and pthread_once() implementations. When single threaded and forking(), make sure that the current thread's signal mask is inherited by the forked thread. Use private mutexes for libc and libpthread. Signals are deferred while threads hold private mutexes. This fix also breaks www/linuxpluginwrapper; a patch that fixes it is at http://people.freebsd.org/~deischen/kse/linuxpluginwrapper.diff Fix race condition in condition variables where handling a signal (pthread_kill() or kill()) may not see a wakeup (pthread_cond_signal() or pthread_cond_broadcast()).
