The disadvantage compared to reload() is that you get direct
references to *all* the new objects in your current namespace.  With
reload() you get only a reference to the reloaded module.  With the
proposed super_reload (at least the version I would like) you get no
new references in your current namespace, just updates on the
references that are already there.

Hmm.  Maybe we could reload(), then loop over the available names, and
replace any that exist in the current namespace.
