Constantly doing "svn checkout / make / test" will take forever - I figured converting to Hg, then using Bisect might be a bit quicker.

For such a high-profile project, wouldn't there already be a hg or (more probably) a git repo out there? Might be easier than doing the conversion yourself, wouldn't it?
