++ to unittest2. Frankly, it's a dependency of sqlalchemy, so it gets 
installed anyway during any installation. Might as well use it IMHO.

This is incorrect. pymox' stubout module can be used to perform library 
patching. You can see examples of this in Glance and Nova. For example:

mock.  I'm not suggesting that mox be replaced, but am wondering if mock 
could be an additional dependency and used when the functionality 
provided by mox falls short.

Might be easier to answer with some example code... would you mind 
pastebin'ing an example that shows what mock can do that mox can't?

Thanks much!
