I find it somewhat strange that Charles is taking this position, when
the i386 port currently has such a strong coupling from a compile-time
definition of HZ (or rather, non-definition of HZ, in the preferred case)
and the version of microtime() that gets compiled into the kernel.
Charles, I find your position on these issues is not internally
consistent. It's a failing of mine, but I tend to ignore
internally-inconsistent arguments.
