And lo, Perry Harrington saith unto me:

Neither is 100, but HZ=100 works everywhere else...

Personally, I think HZ=120 would be much nicer, since you can then
do things every 1/20th, 1/24th, and 1/30th of a second without
having to resort to the UTIME patch...

Alphas with HZ > everyone else was okay when all Alphas were way
faster than the competition. Now that all architectures have been
around for a while, it's time that HZ either got fixed for everyone
or got scaled to the actual power of the CPU...
