If the purpose of vacuuming is just to save space in the registry, would it be feasible to only vacuum sometimes, e.g. after say 10 ports have been uninstalled? Or possibly time-based, e.g. if the registry has not been vacuumed in > 24 hours? My registry is 162MB; I think keeping a few extra unvacuumed entries in there temporarily won't increase that significantly.

It seems to be per `port` invocation, if any ports were uninstalled.
