	(fhandler_socket::sendmsg): Ditto.
	* flock.cc (lf_setlock): Allow to cancel thread running blocking
	file lock.  Try to make code more readable.
	(lockf): Call pthread_testcancel.
	* mmap.cc (msync): Ditto.
	* posix_ipc.cc (ipc_cond_timedwait): Call pthread::static_cancel_self

	* thread.cc: Align list of cancellation points with above changes.
	Mark not-implemented functions, too.
