*youch* A 1.5 GiB pack file?

Your files apparently do not delta compress very well.  I fear that
you are going to bump up against address space limitations soon
on 32 bit systems.  Then you will bump up against the 4 GiB pack
file size limit.  Which means you will need to use several packs
and avoid the '-a' flag when calling git-repack.

Nico was suggesting using the default window size (rather than
--window=64) as larger windows requires more memory during repack.
But you may also need the mmap window code I'm working on.  I better
hurry up and get that into Junio's testing branches.  :-)
