It works sometimes, but not all the time.

It appears that the timer ticks don't always run, or
at least the wall clock can just stop for a while.

Of course, vmstat crashes with a divide by zero too,
since xen guests don't increment idle time and vmstat
ends up doing a divide by zero.  I'll figure out how
Xen timing works and will post a patch, if I've got
the time this week.

Will do.
