                         java.util.Random rnd)

Implements a mechanism to delay a thread in various fashions. * CPU: Burn CPU while waiting. * SLEEP: Sleep uninterruptibly while waiting. * MIXED: Switch between burning CPU and sleeping every millisecond to emulate a desired CPU utilization specified by cpuUtilizationInMixedDelay.

Returns:

Millis spent sleeping, does not include time spent spinning.
