Yeah, it's just an odd hack.

That's true, but I don't think we gain anything from that that we wouldn't
also get from putting them in the active file and just copying the active
file.

That's one of the reasons why I want to keep it with the active file; that
way, the chances of losing that mapping are pretty low.  I don't think the
speed hit on LIST ACTIVE will be very significant; we're already doing
per-line processing of it when we send it to the network.
