This means the the user still has to know about the two sorts of
environments.  They shouldn't have to think about it at all.

Having a user-callable `synchronize-environment' function might be
useful, but I think _only_ as a work-around for cases where the emacs
internal code doesn't do it yet (which should be considered a bug) -- it
ought to remain the job of the C primitives to synchronize the
environments when necessary (note that this is very rare).
