Hum. I hate moving discussions... :-)
I answered the original report with a suggestion and a request that he open
an issue if the suggestion didn’t pan out. It didn't, so he followed up in the
issue system.
Call me old and grumpy. :-)
Anyway, I'm surprised by the interval timer. I had a recollection that it was
normally always at 100Hz on VMS. Oh well. I wonder why on earth you would
want to have a 60Hz clock here...
PDP-11 (and I suspect PDP-10 and other older machines) are a different story,
as they usually use the line frequency of the mains AC as the clock source,
which means 60Hz in the US.
The original user's problem was observed running 32V, not VMS. That is why
I said that most OSes use a 100Hz tick rate.
D'oh! Somewhere I lost track that it was with 32V.
