Don't update Queue on initialization about fyrd

[petercombs]

One way to go about this would be to have an option in Job.__init__ to take queue as a keyword argument, and otherwise fallback to create its own. i.e.
self.queue = kwds.get('queue', _queue.Queue(user='self', qtype=self.qtype))
(although note that you would need to update the allowable keyword args in options.py.

Yeah, that's a pretty good idea. I could also make the default an instance-wide default loaded at the top of job.py, that would add a potential hang point during the initial import, but would make the default be the already created class.

I wonder if there is a way to add a timeout in python for external commands? That would be really helpful here, as I could then add a timeout for the instance-wide version.

Another option would be to make the instance-wide version a placeholder and populate it only if it does not currently exist.
