No, it has nothing to do with the "coolest merge ever". The same problem 
occurs when I'm working on a topic branch:

      A--....--B   <- topic
     /
  --g--....--G     <- integration branch ("good by default")

While fiddling with B, I find a bug and suspect it somewhere on the 
topic from A to B. When A has a change that causes a substantial or 
complete rebuild, testing g causes burden for no good reason.

But, as I said, this is a tangent. I have no mission to change git bisect.
