[time-nuts] TIC model

[Chris Albertson]

You all are "inventing problem".  Solve them AFTER you find a problem you
can measure.   Interrupts are not an issue on a UP like the AVR because
they are completely deterministic.  It don't matter the lenth of time as
long as it is 100% deterministic and predictable.   On a multi-tasking OS
running on a super scaler CPU you have unknowable latentcy but this is not
the problem on a chip that does one machine cycle per clock cycle.
