Does the time work ok with TSC, with the new commits?  Basically there
was a bug in estimating TSC rate, which I think was a multiprocessing
hazard.

I have a system where TSC should be 2.8G, and it was being measured at
boot at 3.9G sometimes (and sometimes 2.8G).   I haven't tried to
backport the patches to 8 and test, but my guess is that I'll have the
right TSC value and timekeeping with TSC will be ok.
