[Zope] Zope won't give up WebDAV Lock

[hpinson at indepthl.com]

I have a regularly occuring WebDAV problem:

A file edited via ExternalEditor gets a WebDAV lock.  Upon closing 
(Textpad in this case) occasionally the lock is not released.

The lock is not listed in Control Panel > WebDAV Lock Manager, 
therefore cannot be released there.

Restarting Zope does not release the lock.

This is getting to be a terrible problem.  Once a lock is in place, 
the file cannot be changed, renamed, or deleted at all subsequently.

Zope is 2.7.6 Final, Fedora Core 3, Python 2.3.3

Here is the only reference that I have been able to find in the log:
