Ah, but certainly doable. Get a halo on the debugger, explore it, find 
CompiledMethodTrailer>>new, find pointers to the receiver, this gets you 
into CompiledMethodTrailer class. Now inspect methodDict, remove #new 
and you're done :-)

(okay not exactly what you would have your mom do ...)

Yup. And I suspect it worked for me when I tried it earlier due to MCs 
unreliable sort order (sigh... the image I used I had updated step by 
step while posting the changes to make sure I could load them). And of 
course *that* part of loading changes (i.e., unload) happens a little 
less careful than installing methods (which defers notifications). 
Double-sigh. I think we should consider changing all this to future 
messages - which makes it safe since it'll be processed when we're good 
and ready and not before.

Exactly. I'm on it, give me a few more minutes.
