Thanks for the patch --- it's certainly a fine starting point.

We can either drop this in core (with a lot of #ifdef LINUX added)
or expect Linux packagers to carry it as a patch.  Given that the
packagers would also have to modify their init scripts to go with,
the patch route is not unreasonable.  Comments?

FWIW, I think that's probably a feature --- I'd vote for only resetting
in regular backends and possibly autovac workers.
