Ok. I understand. Do you do something in #lookupMethodInClass:  that checks
that the current class is Other. To do that you use  objectMemory splObj:
OtherClass
and you put Other in the special object array ?
Then if that's true, you fetch the instVar for network stream + ID (you
assume the instVars offsets),  and you forward the message to the original
object?
