The second example is a doctest for the feature; for me it fails if
#random is removed, and passes otherwise.

Ah, thanks; I recall seeing a comment somewhere about nose swallowing
exceptions in code under test, but I didn't know it would do things

I added that to my local nosetester.py, but it didn't turn up any
