| | | | | | | | | | | | | | | the threading libraries is built. This simplifies the logic in makefiles that need to check if the pthreads support is present. It also fixes a bug where we would build a threading library that we shouldn't have built: for example, building with WITHOUT_LIBTHR and the default value of DEFAULT_THREADING_LIB (libthr) would mistakenly build the libthr library, but not install it.

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.

| | | | | | | | | | | | | | | | | | | | | | | 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.
