Sometimes you can't ... and when you need to keep a cluster of machines
in step with each other its very practical. ULV (Ultra low voltage)
machines typically suffer from shotty clocks, Especially PII / Pentium
Pro based boards.

The comparison is quite relevant because resource usage on (very) small
guests was voiced as a concern. Very small guests with jittery clocks
are very much like ULV biscuits.

Its very appropriate since its drift we're correcting.
