We could introduce a time.maximumSkew variable, and just walk only 
that much further when traversing the commits.

We could have had "commit generation number" in the commit
object header, and use that instead of commit timestamps for
these traversal purposes.

Isn't this "commit generation number" information that can be
regenerated on the fly, i.e. a perfect fit for data to be stored
in a persistant cache, e.g. in ".git/tmp/virtual-commit-timestamps"?
