This kind of loop is a bit unfortunate, since it can potentially spin
infinitely if someone managed to e.g. break event queries, but also
because it can generate a lot of data if you were to turn on the
appropriate debug channels. You should probably use a bounded loop
with a Sleep(), like we do in device.c. (And we're using that in
enough places now that it should probably be a helper function.)
