FYI: Throttling is merely part of identifying what is causing the problem.
Unless your simh VAX cluster member is VERY busy, throttling at 80%
will probably use at least 15 times more host system CPU cycles than
Idling. The 80% number will really use 80% of one CPU core continuously
even when nothing at all is going on in the running VMS environment.
