* pthread/pt-alloc.c: Don't include <bits/atomic.h>. (__pthread_free_threads): Change to a struct __pthread *. (__pthread_free_threads_lock): New variable. (__pthread_alloc): When looking for a TCB to reuse, iterate over __pthread_free_threads taking the first for which the STATE field is PTHREAD_TERMINATED. When reusing a TCB, first call __pthread_thread_halt on it. * pthread/pt-dealloc.c: Don't include <bits/atomic.h>. (__pthread_free_threads): Change to a struct __pthread *. (__pthread_free_threads_lock): New declaration. (__pthread_dealloc): Enqueue PTHREAD on __PTHREAD_FREE_THREADS. Set PTHREAD->STATE to PTHREAD_TERMINATED after everything else. * pthread/pt-join.c (pthread_join): Call __pthread_thread_halt before destroying the thread. When destroying the thread, call __pthread_thread_dealloc on it. * pthread/pt-detach.c (pthread_detach): If destroying the thread, call __pthread_thread_halt before deallocating the stack. In this case, also call __pthread_thread_dealloc on the tcb. * pthread/pt-exit.c (pthread_exit): Call __pthread_dealloc only if the thread is detached and then as the last thing we do before calling __pthread_thread_halt. * pthread/pt-internal.h (__pthread_thread_halt): Remove argument NEED_DEALLOC.
