Memory usage of an 'empty' python interpreter

I was wondering what the approximate amount of memory needed to load a Python interpreter (only, no objects, no scripts, no nothing else) in a Linux 2.6 environment. According to ps, it appears to be 3312 bytes, which seems absurdly low to me. However, when I check the size of my Python executabl
