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.
