Yes, I hadn't forgotten about that, but I think it will be a bit before 
I get back to setup...

There's been a few ad-hoc solutions over the years, I think, but unless 
it's built into setup somehow, it's not going to reach the majority of 
users, I think.

It's been pointed out recently that the top-level cache directory should 
probably be the release label (e.g 'cygwin') rather than the mirror URL.
(There's some historical cache layout compatibility stuff in Cygwin for 
an even older scheme, but I can't remember the details...)
