* manager.c (__pthread_manager): Do block __pthread_sig_debug.
Don't restart the thread which sent REQ_DEBUG.
(pthread_start_thread): Check if __pthread_sig_debug > 0
before debugging.
* pthread.c (__pthread_initialize_manager): Suspend ourself
after sending __pthread_sig_debug to gdb instead of
__pthread_sig_cancel.
