Yes. I started splitting it into separate files, with a view towards
untangling the mess. Unfortunately, I didn't finish.

Actually, using /proc on FreeBSD isn't a very good idea, since procfs is
deprecated, and rumour has it will eventually go away. FreeBSD folks
evidently believe /proc is a security hazard. That's why it isn't
mounted by default, and isn't used by anything in the standard FreeBSD
userland.
Problem is, the alternatives, sysctl or libkvm, both make use of binary
interfaces, and that introduces some major headaches. The best approach
I've been able to think of is to move the pid_is_* functionality into a
library, at least for freebsd-i386. That way kernel upgrades won't
require recompiling dpkg every so often... We'd have to fix the library,
but that's not quite so obnoxious.

Good idea.

Does this patch handle wildcards? i386-freebsd5.0-gnu and the like are
going to be a problem. I'd look at your patch, but bts looks down.
