Since message sends in Interpreter and ObjectMemory are translated to C
function calls, which does no receiver dispatching, the receiver always
has to be self, hence the choice to make ObjectMemory a superclass.  If
you separate ObjectMemory out to another object you will have to update
the CGenerator so it knows that message sends to objectMemory are just
regular function calls.  You will still have to maintain that
method names are unique across both Interpreter and ObjectMemory,
unless you put them in seperate C modules and utilize private functions.
