  There were two reasons for adding this code:

    1.  Avoid duplicates (speeds imports if there are duplicates and
        the modules are found on an entry after the dupes).

    2.  Avoid breakage when a script uses os.chdir().  This is
        probably unusual for large applications, but fairly common for
        little admin helper scripts.

  I certainly agree that this can be improved; if Jack or Just would
like to assign it to me on SourceForge, I'd be glad to fix it.
