There are other users of this functionality. We have an emulator
running on top of linux which in turn runs code originally intended for
another OS. It cares about walltime, so it wants to know ASAP if the
linux system time changes.

We've actually been carrying an internal patch doing something like this
for years now...never pushed it to mainline since we didn't think anyone
else would be interested.
