A Python ‘import’ is conceptually two steps: execute the module, then
bind the objects that were created to names in a namespace.

The import mechanism has a short-cut: if the module has already been
imported by this Python VM, the module isn't executed again, and the
existing objects are simply re-used with new bindings as necessary.

What you want is to specifically request the module to be re-executed
to re-create the objects again, and re-bind the existing name bindings
to the objects that result.
