I understand what needs to be done in terms of mocking, I just don't see a way a terribly easy way to do it. Thus, I am more in favor of the envvar.

@micheles, @matley
I'm fine with either putting the flag in OqJob or an envvar. I'm slightly more in favor of an envvar, however, and I would prefer the name `OQ_NO_DISTRIBUTE`. If we can all agree on that, I'll make the change.
