You can start lots of them, even multiple ones to service the same
queue.  They won't collide and don't need to lock any resource.

But each is a separate Python process, in the current scheme of
things.  If the qrunners were I/O bound, you might see some gains by
multithreading them, but I haven't implemented that at all (and it
won't help if they're cpu bound).
