what kind of memory limitations to processes running on 32-bit python (with 32-bit C extensions like scipy) have on 64-bit Windows?   I'm having occasional MemoryErrors when running a python program on 64-bit Windows 7 that runs fine on my OS X machine.  Both machines are using a 64-bit OS and have 4GB of RAM.
