Thanks, for the reminder, but this was internal Zope code that had
inadequate tests. It is also code that isn't being used in production
at this time because it is incomplete.  (This is sad, because I think
zsync has tremendous potential.  We should probably move it to a development
branch and remove it from the main tree until it's ready. Sigh.)
I think he stumbled accross this while addressing a collector issue.

I really want to know if any Zope 3 applications outside of Zope 3 itself
are using this API.
