We tried using SET CLOCK FAST to bump the cpu clock speed on our
VAX 11/785 running 4.3BSD/NFS from Mt. Xinu.  Everything seems
to work great -- no crashes, and the system is much faster, *except*...

The time-of-day clock gains about 1.5min/hr .  My browse through our
kernel sources didn't suggest any obvious reasons for this, and I can't
think of any offhand -- isn't the tod clock supposed to be generated by
a hardware interrupt independent of the CPU?	What am I missing?  What
can we do to fix this?
