Stephane, your paper was fundamental in implementing SqueakElib.  I 
decided to intercept the message lookup, rather than the 
wrapper/instrumentation approach.  It turns out that a wrapper is still 
needed, but the other goal is to secure these references into the vm, 
and the approach taken supports that too.
