DirectoryView was giving me a lot of pain while I was editing some skins:

2002-09-04T18:26:12 ERROR(200) DirectoryView Error checking for directory modification
(...)
OSError: [Errno 2] No such file or directory:
'/usr/lib/zope/lib/python/Products/CMFPlone/skins/plone_3rdParty/CMFCollector/.#collector_edit_form.pt'

(For the non-Emacs-enlightened, this is a backup file.)

I finally got tired and patched it so that it doesn't try to check backup
and hidden files for changes. Patch attached.

               lose both and deserve neither.
