There are some serious memory leaks w/ the CVS HEAD Gump code. Python is
non-trivial in keeping healthy (is my experience, or maybe I just trod on
land mines). Anyways, the simple documentation of results (generating pages)
has some awful memory leaks. I think the process bogs down to a crawl.

The 'CleanUp' branch started as adding lots of __del__ to try to break
circular dependencies and reduce these leaks. I think the situation is
better. A lot more went into this branch (moving to DOM from Pythonic
pseudo-(D)OM). Also, the update get performed right before the build, and
the e-mails get sent right after the build completes (given the largest
window to fix before next build). A bunch of stuff like that.

I asked yesterday about merging CleanUp into CVS HEAD in the main 'cos you
are working so diligently on this, and I am nervous I'll break you. After
tonight I'll be done w/ my EMT refresher & will be able to commit to fixing
what breaks. I am tempted to perform the merge, but turn off notification
(which might send duplicates for some odd reason) and see what transpires.

regards,

Adam
