What really needs to happen next is to think about which bits of
selfuncs.c should be exposed --- what's generally useful, and do we
think that it has an API clean/stable enough to expose? The reason I
kept all that stuff static so far was because it got whacked around
every release or two, and I didn't want to be constrained by worries
about breaking outside modules. I'd still prefer to minimize the number
of routines exposed, so some thought is needed.
