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.
