I agree that's the right place for real user processes, but I note that there are drivers that have kernel threads that do basically this: if (signal_pending(current)) dequeue_signal(current, ...); for example, drivers/block/nbd.c, and obviously they don't want to still see signal_pending(current) after they have dequeued all the pending signals.
