Note that we already do that in a couple of places where it makes sense
- in those cases the underscore is there to tell *clients* of the class
"don't call this directly", but it is still explicitly documented as
part of the subclassing API.

(the only example I can find at the moment is in asynchat, but I thought
there were a couple of more common ones than that - hopefully I'll think
of them later)
