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".
