It's *much* faster than reference counting everything. Reference 
counting is more or less the slowest garbage collection technique there 
is (except if only very few objects have to garbage collected). It also 
can't deal with circular references.

Reference counting too.

You get the same problem if you pass a reference counted structure to C 
(or any other language).
