This sounds like 32 bit -- have you tried a 64 bit Python_numpy? Nt that
you wont have issues anyway, but you should be abel to do better than
1.3GB...

I don't think so, no -- but are limited to 2GB (I think) if you're using a
32 bit process
There is also a compressed array package out there -- I can't remember what
it's called -- but if you have large compressible arrays -- that might help.
