Ordinary users won't be building Python from source. Developers won't
care so long as we clearly document the sundry suffixes and describe
them in the README (or in a PEP, with a pointer from the README).

Having some characters on the end to flag different kinds of custom
build seems like it fits within the .so naming conventions I'm aware
of, but I'm sure the *nix packaging folks will pipe up if Barry starts
wandering too far afield in this area.

Having multiple parallel "altinstall" installations be genuinely
non-interfering out of the box certainly seems like a desirable
feature to me.

Cheers,
