Review comment:
`type(self)._create_process` is a "trick" to avoid multiprocessing
pickling more than it should (taken from the MP source code), which was
important when the factory method was being sent from the Scheduler to the
DagFileProcessorManager over a multiprocessing connection
But since we are now just creating the processor, rather than passing a
reference to the the factory, we can do as Jed suggests.
And `self._some_static_method` works fine.
