       When  an object attempts to shadow `ob' (with the shadow()
       efun), valid_shadow in the master object is  called.   One
       object  parameter is passed, which is the object that pre-
       vious_object() is attempting  to  shadow.   valid_shadow()
       should  return 0 if the shadow should not be permitted, in
       which case the shadow() call will return 0 and  fail.   If
       valid_shadow() returns 1, the shadow is allowed.
