If this change is undesirable, we can (for example) do

	--- kernel/posix-timers.c
	+++ kernel/posix-timers.c
	@@ -885,6 +885,7 @@ itimer_delete(struct k_itimer *timer)
		timer->it_process = NULL;
	 
		unlock_timer(timer, flags);
	+	tmr->sigq->flags |= SIGQUEUE_CANCELLED;
		release_posix_timer(timer, IT_ID_SET);
	 }

instead, and still fix the "BUG 10460".
