This makes flashrom sleep more eagerly rather than busy-waiting, observing that most delays in flashrom are either less than 100 microseconds (barely enough time to get any work done, even on a fast machine) or much more than 1 millisecond (very wasteful to busy-loop). Since we believe most systems offer good timer resolution that should provide sleep latency on the order of 100 microseconds, this is a reasonable default. For DOS, the default is set to 50ms because the best available timing source on DOS only ticks at about 20 Hz.
