Hi Phil,

I tried your code, and the references I see to objects equal to `0 at 0` 
are from CompiledMethods. Do you want to change those? Why? What object 
do you want to make the methods point to? Isn't it enough to just 
recompile the methods?

Or you are referring to objects other than CompiledMethods? Which, then?

Thanks,
