I think your first question should be: is the waterfall the best view?

For most purposes, either the console or one of the grids is the most
useful display - they show the things developers are interested in -
commits and builds - while omitting the things that developers don't
care for - relative timing of various steps.

That said, the waterfall is probably the most beastly piece of code in
buildbot right now.  It does not "play nice" with any other component
of Buildbot, and uses a *lot* of data to produce its output.  Further
complicating it is only likely to make it slower and more of a
resource hog.  I would not advise that anyone hack on the waterfall,
least of all someone new to Python.

I don't mean to dissuade you from your pursuit -- just to say "this
way lies madness."
