The other thing is that bisect arose (in the context of VCS) in the git
world, where I gather part of what makes it effective is that development
happens in terms of merging branches, so there's less "cross contamination"
between different streams of changes. I'm not sure how useful automated
bisection would be with a "everything goes on to ToT" world of LLVM's SVN.
