Python & 64-Bit Linux: Using >4 GB of Memory?

I'd like use more than 4 GB of memory for a single python process. Is this possible with a 64-bit processor? I'm using a Woodcrest processor, which I presume supports 64-bit addressing. I've installed the "hugemem" kernel distribute by Red Hat. Yet my Python processes get terminated upon using 4 GB of memory (system has 8 GB). What can be done?


Below are some stats about the computer. Thank you for any help.

Shouldn't get anywhere near that big. Did you compile a sub-version of Python 2.5 or get a distro from some place?
