What versions of python and numpy are you using?

With python 2.5.1 and numpy 1.0.3 under Fedora 7 x86_64, I just now memmap'ed a 10 GB image cube without any trouble. I can't comment about what will or won't work under Windows, but I've been doing > 4 GB files with linux ever since 64-bit support showed up in the early betas of python 2.5 and numpy 1.0. memmap'ing certainly isn't broken for me - removing it would be devastating.
