Turning on multi-core support greatly increases the memory
consumption; at least double the single thread case.

Going over the original repository and deleting (get all copies out of
the history) those giant i18n files generated by programs than Sean
refers to would be my first step. If you have 5,000 revisions of a
10MB file I suspect it would take a huge amount of memory to pack.
Plus you have to copy all of that pointless history around.
