 Before giving up completely, perhaps it would be worth trying changing the
 "sleep(1)" into a much smaller usleep() or nanosleep() - which would have
 the same effect, of avoiding busy waiting, while not adding nearly as much
 delay (if it happens that the sleep needs to be a second occasionally, then
 that might mean 100 * usleep(10000) rather than 1 sleep(1), but it seems that
 most of the time, the wait does not need to be nearly that long).
