Hmmm, what you are saying doesn't make sense. An interpreter has
to exist in order to import a module into it.

If you look at the code what I think you will find is that when
the child process init function is called by Apache, that it will
iterate over the list of modules associated with PythonImport
definitions, creating the named interpreter and then importing
the module into it.
