It's really the same thing, and a bug.  A method called `compare' is in 
the underlying Swarm object proxy (Objective C side), and QSort sends it 
directly to that proxy via -perform.  It should get forwarded to the 
Java object.   I don't think -perform has to behave that way for any 
performance reasons internal to Swarm, but I'd have contemplate the 
sources to be sure.
