Hi all,

I'm joining Mark's assertion - this is a real issue for me too. I've stumbled into this problem too. 
I have a numpy/scipy kind of application (about 6000+ lines so far) which needs to allocate alot of memory for statistics derived from "real life data" which is then transformed a few times by different algorithms (which means allocating more memory, but dumping the previous objects).

Currently I'm getting MemoryError when I try to use the entire dataset, both on linux and on windows, python 2.5 on 64bit 4gb mem machine. (The windows python is a 32bit version though cause it needs to be compatible with some dlls. This is the same reason I use python 2.5)
