I guess I should answer the nit: Yes, it contains names and pointers to
files, rather than their contents.  I lumped this under `implementation
differences', although it is in fact a generalisation.

Now that everyone has had time to disagree with what they think I said:

I suppose I should relent.  In fact, I too think it would be too
expensive (though `too expensive' is rather a matter of opinion).
But I have not tested it, and I will not say that it *is* so without
seeing some comparisons.
