| | | | | | | | | | Warning, after symbol versioning is enabled, going back is not easy (use WITHOUT_SYMVER at your own risk). Change the default thread library to libthr. There most likely still needs to be a version bump for at least the thread libraries. If necessary, this will happen later.

| | | | | | | | | | | | they become candidates for reuse. Without this fix, some of the state from a thread structure's previous incarnation could interfere with its new one. Specifically, a non-bound thread started as "suspended" (see pthread_attr_setcreatesuspend_np()) might not get scheduled at all when resumed, as the "active" flag would be set spuriously.

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.
