How can looping, waiting for a task to be ready prevent anyone from 
using the CPU?  You realize this is on a limited number of cores in the 
GA144 where each core uses relatively little power, right?

I'm not sure what you are objecting to.  If there's anything available 
to waste on a GA144, it is CPU cycles.  That is the underlying premise 
of the chip architecture - that CPU cycles are so cheap they can afford 
to be "burned" if that has a purpose.
