doesn't work with multiprocessing nose plugin

[jbeluch]

The multiprocess plugin mentions that it might not play nice with other plugins...

That's no fun. I have yet to try it out with the MP plugin myself, FWIW (most of my other projects that use nose don't work well with it either), so it's not just you :( Can't think offhand why it would break though. Let me know if you end up digging into it!
