It's a little worrying that all of these approaches add a new task waking up 100 times a second or thereabouts. Even ignoring the extra icache hit this imposes, doesn't this somewhat torpedo all the effort that's been going on to increase the amount of time the system can go without being woken up?
(At the very least this whole thing ought to be turned off on power-sensitive devices: but in the end, won't that be pretty much *all* devices, especially embedded ones, which is one domain where realtime stuff becomes important?)
