 Chris, I failed to reproduce the behaviour you describe.  Would you (or
 anyone else following) mind providing a code snippet that exposes the bug?

 I started with:

 import numpy as N
 from math import exp

 invlogit = lambda x: 1.0 / (1.0 + exp(-1.0 * x))
 vi = N.vectorize(invlogit)

 for i in xrange(100000):
     x = vi(N.array([1,2,3]))
