I'll try it. To be fair, for our application 100% cpu might not be a bad
Next week when I'm in the office I'll give it a go. Perhaps tweaking the
will free some cpu if a problem. The
ioRelinquishProcessorForMicroseconds(us) will still get called.
More important for the app is timely responses to delay semaphores.
Thanks for the responses!

The other thing you're likely to get back is 100% CPU usage. But by
all means, try it.
