In terms of performance, yes, but in terms of power, no.  If NTP gets
the CPU out of a deep stand-by state, then it may take hundreds of
milliseconds for the CPU to go back to that state.  Moreover, NTP 1s-
timer may prevent the CPU from going to even deeper stand-by states.

With this in mind, if NTP wakes the CPU up in order to do nothing,
it's not doing the right thing, IMHO.
