Drat... this text seems to have leaked from stgit and replaced
the one I had written in git publish:

---

We currently restart the unreclaim loop all over when we detect
that the current iteration yielded execution. This is because
a new fid might have been added to the head of the list.

This is sub-optimal : add new fids to the end of the list instead
to avoid that.

---

I'll have to sort this out...
