Could be done. However there's a problem: I wouldn't like the refcont 
nanny itself to be refcount nannied, to avoid infinite loops.

I suppose I can put in locks to (rather easily) overcome this, still 
compiling the refcount nanny in a seperate stage with different flags 
and linking it in seems rather more elegant *shrug*.
