Yeah, that code is ugly as sin already. Maybe there is a way to
refactor it so it can scale better? I can't help thinking of Polya's
inventor's paradox ("the more general problem may be easier to solve").
If we want to do it without any new system-call dependencies I think
that's probably the only way. I'm not necessarily against new
dependencies, if they're portable --- but it seems these aren't.
