While it's probably not an improvement on the order of magnitude you're
looking for, there's a patch (1121142) that lets you read large items
out of a zip archive via a file-like object.  I'm occasionally running
into the 2GB problem myself, so if any changes are made to get around
that I can at least help out by testing it against some "real-life" data
sets.
