Hrm. With the OpenOffice.org buildbot, we have one bot for all  
branches. We never build CVS head, we always either build a CVS branch  
(internally known as a Child Work Space/CWS) or a CVS tag of a  
milestone (internally known as a Master Work Space/MWS). The new 0.7.6  
buildbot waterfall page now has support for looking at only builds for  
one branch, which gets around the problem. We also send our results to  
a tinderbox for a different view of the data.
