I'm guessing that ObjectShell is the ultimate blank slate.  It is the root of 
the object system and only provides the absolute minimum number of methods 
(probably only __id__ and __send__).  All normal objects inherit from Object 
as they do now, but special objects that don't want all the Object stuff by 
default (e.g. things like Builder or dynamic proxy objects) could inherit 
from ObjectShell.
