[py-dev] Generative tests

[Maciek Fijalkowski]

I would like to re-think a bit generative tests and here are my ideas.

1. There should be *no* setup_function called for generator, rather 
setup_generator and setup_generated_function called in a) test 
collection (before generator itself is called) b) run of a single function

2. Distributed testing should treat generators as single function, ie 
not split them between hosts. This will solve a lot of issues, also 
regarding speed.

What do you think?

PS. Names are rather ad-hoc, I'm happy with different choice.
