Cygwin can't handle huge packfiles?

Hi,

I'm trying to get Git to manage a 5Gb source tree. Under linux, this works like a charm. Under cygwin, however, I run in to difficulties. For example:

$ git-clone sgp-wa/ sgp-wa.clone fatal: packfile ./objects/pack/pack-56aa013a0234e198467ed37ae5db925764a6ee98.pack cannot be mapped. fatal: unexpected EOF fetch-pack from '/cygdrive/e/Projects/sgp-wa/.git' failed.

To figure out what is happening, I printed the value of errno, which turns out to be 12 (Cannot allocate memory). I'm not sure how mmap is implemented in cygwin, but if they allocate memory and load the file into it, then this error is not surprising, as the pack file in question is 1.5Gb in size.

I'm not sure how to approach this problem. Any tips would be greatly appreciated.

Thanks a lot!
