The code is not different from mkiv but instead we swap dimens using a 
primitive. When you set \overloadmode=4 (which can be interesting as it 
might reveal issues in a style) the run will quit with an error ... this 
is a fix:

      % Swapping fails in overloadmode and is also wrong (as it then is 
persistent due
      % to global being inherited).

(it also indicates that we're cheating with the sizes which when it 
happens global is pretty dangerous ... it works but i admit that it is 
not nice)
