I believe that psyco only accelerates functions and methods. So, it's 
not going to do anything in the case you presented. This makes it 
particularly suprising that it broke. Try wrapping up your loop in a 
function. And with Psyco range is (or at least used to be) better. Like so:

import psyco

def f():
     d = 0.0
     for i in range(1000000000):
         d += i
     print d
psyco.bind(f)

f()

That ran in about a minute here. Psyco won't speed up floating point 
operations near as much as integer ops at present, hence its speed 
deficit with respect to java.
