I'm curious as to what you mean by this.  Doesn't this imply keeping track
of the inheritance tree for every object?  I've also had poor luck in
recompiling the auto object.  For example:  I start the MUD, I recompile the
auto object (*), and I type 'who'.  I get the following error:

/bin/player/_who.c, 4: inherited different instances of /sys/auto/auto

(*) When recompiling an object, if it's inherited by an object (in this
case, the auto object fits this description) it's destructed as per the
following code:

    [...]
    oObjectToUpdate = find_object(sFile);

    if(!oObjectToUpdate)
      write(sFile+" is not loaded.\n");
    else
    {
      if(catch(compile_object(sFile[0..strlen(sFile)-3])))
      {
        destruct(oObjectToUpdate);
        write(sFile + " will be reloaded at next reference.\n");
      }
      else
        write(sFile + " has been updated.\n");
    }
    [...]

Perhaps I've made a fundamental error or I'm missing something that is not
explicitly stated.  Thoughts?
