Well, my comment would be that you've apparently only seen very
bad implementations of a perfectly reasonable technique. When
the I/O thread has no more work to do, it should go to sleep,
to be awakened by the next I/O completion. With proper signal
support, no busywait is needed, and bad timing is irrelevant
if you're acually getting the device notifications.
