New Revision: 57272

Modified:
   sandbox/trunk/import_in_py/tests/test_fs_loader.py
Log:
Add a (failing) test for the loader to continue to work even when the state of
the filesystem has changed since the initialization of the source loader.

Discovered thanks to test_runpy, the test that keeps on giving me pain and
agony.
