The problem with Interlock is that it doubles the number of exchanges
required.  Fortunately there's a simple optimisation that addresses this, you
just need to bundle the two message halves into the same exchange.  If there's
any interest in this optimisation I can probably get an RFC for it out by
about April 1.
