Resource Usage
The interval counter is driven off of the real time clock. If interrupts are disabled for long periods of time,
the timing wont be accurate. I/O routines that disable interrupts typically track RTC ticks and then update
the RTC when the I/O process has completed. At this same time, the interval counter will be updated as
well accounting for, at most, one missed expiration.
There is a single, system-wide interval timer. Only one task can be awaiting an interval at a time. If a
task is already waiting, another call to WaitForInterval() will return immediately.
