	rda/unix       : ChangeLog lwp-pool.c lwp-pool.h thread-db.c 

Log message:
	Remove code to handle threads exiting without generating a wait
	status; that was a kernel bug, not an intended feature, and
	there's no easy way to support both.
	* lwp-pool.c (lwp_pool_continue_and_drop): Delete function.
	* lwp-pool.h (lwp_pool_continue_and_drop): Delete declaration.
	* thread-db.c (enum death_state): Delete type.
	(struct gdbserv_thread): Remove 'death_state' member.
	(add_thread_to_list): Don't initialize it.
	(death_state_str, debug_report_death_state_change,
	death_state_got_event, death_state_notified): Delete functions.
	(handle_thread_db_event): Don't handle death events specially, and
	don't handle the notifying thread specially.
	(continue_thread): Don't treat threads whose death has been
	foretold and who have completed their notification specially.

	rda/unix       : ChangeLog lwp-pool.c lwp-pool.h thread-db.c 

Log message:
	Move libthread_db event-based thread death logic from lwp-pool.c
	to thread-db.c, so the former can stay innocent of libthread_db's
	details, and limit itself to kernel behavior.
	* lwp-pool.h (lwp_pool_continue_and_drop): New declaration.
	(lwp_pool_thread_db_death_event,
	lwp_pool_thread_db_death_notified): Declarations deleted.
	* lwp-pool.c (enum death_state): Move to thread-db.c.
	(struct lwp): Delete 'death_state' member.
	(hash_find): Don't initialize it.
	(interesting_queue): Don't provide an initializer for it.
	(check_stop_pending): Don't abort if wait_and_handle didn't put
	the thread in a stopped state; that could be caused by kernel
	behavior (say, threads exiting silently), not necessarily a logic
	flaw in lwp-pool.c.
	(death_state_str, debug_report_death_state_change): Move to
	thread-db.c.
	(lwp_pool_thread_db_death_event,
	lwp_pool_thread_db_death_notified): Move to thread-db.c, and
	rename (see below).
	(check_for_exiting_nptl_lwp): Delete.
	(lwp_pool_continue_all, lwp_pool_continue_lwp): Don't call
	check_for_exiting_nptl_lwp.
	(lwp_pool_continue_and_drop_lwp): New function.
	* thread-db.c (enum death_state): Moved here from lwp-pool.c.
	(struct gdbserv_thread): New member death_state.
	(add_thread_to_list): Initialize it.
	(death_state_str, debug_report_death_state_change): Moved here
	from lwp-pool.c.
	(death_state_got_event, death_state_notified): Renamed from
	lwp_pool_thread_db_death_event and lwp_pool_thread_db_death_notified,
	and changed to update the death state of a 'struct gdbserv_thread'
	instead of a 'struct lwp'.
	(handle_thread_db_event): Call death_state_got_event instead of
	lwp_pool_thread_db_death_event, and death_state_notified instead
	of lwp_pool_thread_db_death_notified.
	(continue_thread): If the thread's death state indicates that it's
	going to disappear without further ado when continued, continue it
	with lwp_pool_continue_and_drop_lwp, not lwp_pool_continue_lwp.
