The latest version of nose starts with the following note to users:

Nose has been in maintenance mode for the past several years and will likely cease without a new person/team to take over maintainership. New projects should consider using Nose2, py.test, or just plain unittest/unittest2.

I was wondering if after v0.10 we should consider moving to py.test or we should remain with the version of nose that's currently in lib/external.

In case there's consensus around this, I wouldn't mind experimenting with py.test to see how much this change will be doable / painful.
