Well, the point where trackdown succeeds is just a working
starting point from which one can compare or try to pull
various patches until the error appears.  Conflicts that
prevents a clean build can possibly cause lots of "unnecessary"
unpulls.  The trackdown command has no smartness in it yet.

I've been pulling quite many patches from "my" starting point
without hitting the bug so far.  Maybe this approach turns
out not to be the best for finding this bug.
