Update.
* sysdeps/pthread/createthread.c (do_clone): If __ASSUME_CLONE_STOPPED
is not defined, do explicit synchronization.
(create_thread): Do not lock pd->lock here. If __ASSUME_CLONE_STOPPED
is not defined also unlock pd->lock for non-debugging case in case
it is necessary.
* pthread_create.c (start_thread): Always get and release pd->lock
if __ASSUME_CLONE_STOPPED is not defined.
(start_thread_debug): Removed. Adjust users.
* allocatestack.c (allocate_stack): Always initialize lock if
__ASSUME_CLONE_STOPPED is not defined.
* Makefile (tests): Add tst-sched1.
* tst-sched1.c: New file.
