I don't know whether my distributable certificate deletion proposal
(http://lists.gnu.org/archive/html/monotone-devel/2005-02/msg00124.html)
solves the issues which are to be solved with epochs. They should be
able to avoid reinserting invalid revisions into the main server
(because they still exist but are hidden) and they should be able to
cause all clients getting an up to date idea of history. So, IIRC, they
are able to propagate a rebuild.

[But I'm not sure whether certificates which do not belong to a revision
of the requested branch on the server get transmitted to a client which
still thinks that this revision is part of the branch (if not a
certificate to delete a revision from a branch will never get
transferred by syncing with that branch)]
