tox - restart nose after every test

Shouldn't be necessary but I'm putting it in in case I decide to
use multiple processes in the future.
test/log - use threading and a multiprocessing queue to combine logs

This is to get logging working with the distinct web server process.
handlers/run - use hard-coded implementation to pass tests

Next stage will be to use triangulation to drive out this particular
hard-coded implementation. Still not sure how I'll be implementing
process running but the simplest implementation would be to run them
as children, so may start there.
