I guess the question is at what layer the retry logic should occur.  We
could retry a save at the dao layer, but then there are questions like
what happens when the first request did a MOVE?  In that case,
shouldn't we return a not-found error?  That would mean the retry
logic has to be at the dav layer.  I guess one thing we could add is
to catch a stale-object exception and return 412 if that request had
an If-Match header.
