It got *much* worse when CMF shifted to use subversion, which has many
more bookkeeping files in the .svn directories.  Plone developers who
work on Windows sent up an anguished cry just after we switched over,
while they were trying to prepare their 2.1 release candidate.

I applied a tourniquet, which was the major reason for pushing out the
1.5.3 release.  Mark Hammond volunteered (at the Plone Symposium in New
Orleans) to look at the feasibility of a better solution which would use
the native Win32 file monitoring APIs:


As Chris noted, running with 'debug-mode off' also avoids this issue, if
you can't upgrade CMF for some reason (and you *should* be running this
way if performance matters, anyway).
