I think you are way too concentrated on this particular incident,
and you are generalizing it into something that is not so in
practice.

Even in this particular case, there's just 3 other commit points in
the Git tree between commit 8a1ca8c (the breakage on PowerPC) and
e14112d (the fix). We'll have up to 10,000 commits.

I bisect on an almost daily basis, and i'm not seeing unreasonable
problems.
