I will admit to not understanding this very well, but my understanding
was that pushlog handles differentiating *pushes* from *commits*,
since developer A could potentially push 20 commits by developers B
and C, and developer A should be considered the responsible party
there -- and at least in Mozilla's case, only the last of the 20
commits should be built.

The pushlog extension has caused a fair bit of pain for Mozilla, as it
tries to keep in sync with the mercurial repo, and sometimes fails.
So I'm not sure we should be recommending adding it.
