[Vm-dev] Linux VM and Delay.

I'll try it. To be fair, for our application 100% cpu might not be a bad
thing ;-)

Next week when I'm in the office I'll give it a go. Perhaps tweaking the
idle process
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.
