There are still two hops, but making it a compound op keeps the
server-to-server communication in the compounding translator (which
should already be able to handle that case) instead of having to put it
in the MDS.  It's not so much a matter of improving performance -
turning a client/server hop into server/server or server/cache should do
that - but of implementing that improvement in a clean way.
