Sorry about that, here is a summary of my complete code. I haven't cleaned
it up much or anything, but this is what it does:
import time
import multiprocessing
test_constx =0
test_consty =0
def functionTester(x):
global test_constx
global test_consty
print "constx " + str(test_constx)

I just saw this:
http://bugs.python.org/issue8094
which seem to be similar to what I'm having. Does anyone know if there is a
fix for it?
Thanks again

Thanks but I'm having trouble with that module too. Currently what I
have is something like this:
import sys
import os
import multiprocessing
import time
def functionTester(num):
return ((num+2)/(num-2))**2
num_args = [61,62,33,7,12,16,19,35,36,37,38,55,56,57,63]
