"Module initialization" is what happens when you import a module the
first time. In pure Python modules the module level code is executed and
in extension modules a special initializing function may be called.

Sounds unlikely if you *really* update the attribute of the module and
not just rebind a local name that was bound to the object in the "global"
module before. Example:
from spam import egg
egg = 42 # This does *not* change `spam.egg` but just the local binding!

Module initialization is only done once, there's nothing to ensure.
