I don't know if I've made this more complex than I really need to
but I've permitted multiple windows per pack.  There is just one
LRU of all windows across all packs and a maximum amount of address
space to use for pack mappings.  Least recently used window gets
tossed when we need a different window.  This permits us to keep
say a window active on the front of a pack (near the commits) and
another different active window closer to the back (near the blobs).

Sounds good. That is exactly what I was expecting it to be done.

So I have this implemented but its against the 32 bit index.
It passes the full test suite and appears to be working as intended.

I am going to rebase the changes to the 64 bit index in `pu`
and clean up my history.  Its currently one massive commit with
lots of changes that should be broken down into slightly more
digestable chunks.

I'll try to do that tonight and get a patch series out.  My email
is currently proving to be unstable so you may not get the series
until later on Wed.

Take your time.  My usual git day is Wednesday but this week it
is shot and I won't be doing much gitting until later this week.
