I've worked with that code a little bit, and it's mostly unreadable
spaghetti :-(. If somebody wants to make an effort to make it not
so awful, that'd be great, but I fear it's a very nontrivial project.

Having said that, we've already basically forked it from the NetBSD
upstream, so there is no reason not to diverge further.

True.
