Yes, but that's a decoy here:  you don't really need to import a module;
 you just need to get an *instance* which happens to have its class
defined in that module.  In fact, you already *have* got hold of that
instance (see below).

The reason imports are restricted in "untrusted" code is that the
standard library includes modules whose APIs are dangerous (e.g.,
imaging 'shutils.rmtree').  So, in order to use a filesystem module in
TTW code, you must first make a declaration in Zope filesystem code
which enables it.
