* Calculate the number of cycles to process for each "burst" of CPU activity. The size of a burst
* is driven by the following values:
* is driven by YIELDS_PER_SECOND (eg, 30).
*
* CPU8080.YIELDS_PER_SECOND (eg, 30)

*
* At the end of each burst, we subtract burst cycles from yield, video, and status cycle "threshold"
* counters. Whenever the "next yield" cycle counter goes to (or below) zero, we compare elapsed time
* to the time we expected the virtual hardware to take (eg, 1000ms/50 or 20ms), and if we still have time
* remaining, we sleep the remaining time (or 0ms if there's no remaining time), and then restart runCPU().

* Similarly, whenever the "next video update" cycle counter goes to (or below) zero, we call updateVideo(),
