Do you mean `git bisect'?  I tried using it for Emacs not long ago, but
after a while odd build errors started cropping up.

Eventually, I got to a point where I had to run `make bootstrap' before
each build, and it started taking too long.

Is there anything in particular that I'm missing and can be used to
speed up the build?  Thanks in advance.
