OK, so the question becomes how can I have testsite (which I will fix with your suggestions for the removal of existing files and directories; when I rewrote that chunk of code I had EAFP on the brain) test to make sure that a module is imported?

By making sure the module it imports isn't in sys.modules before it tries to import it. Beforehand:

old_version = sys.modules.get(self.imported)
if old_version is not None:
    del sys.modules[self.imported]

Then make sure the .pth file puts self.imported back in sys.modules.

At the end,

del sys.modules[self.imported]
if old_version is not None:
    sys.modules[self.imported] = old_version
