Okay, it looks like Python 2.6 provides a logging handler we can use for
this -- WatchedFileHandler. It checks to see if the file has been
moved/renamed/deleted and then reopens. It's intended for use with logrotate
A couple caveats. First, it's only in Python 2.6. We can look into whether
it's easy or not to backport this. Second, it's only available for Linux,
which I suspect isn't a problem for you.
I can look into getting this in to the upcoming 1.0.7 release, and the 1.5
beta 2 release.
