A style I have used in my own code in the past is a Singleton class
with register and create methods, where the register takes a
name(string) and the class and the create method takes the name and
*args, **kwargs and acts as a factory.
So I decided to play with this design a little and since I made it a
singleton I decided to place all the thread/process tracking and exit
handle code in it instead of having the odd semi-global scoped
_shutdown, _thread_references, _remove_dead_thread_references and
_python_exit objects floating around in each executor file, seems to
work well. The API would be
from concurrent.futures import executors
executor = executors.create(NAME, *args, **kwargs) # NAME is 'process'
or 'thread' by default
To create your own executor you create your executor class and add the
following at the end
Getting rid of the process-global state like this simplifies testing
(both testing of the executors themselves and of application code which
uses them). It also eliminates the unpleasant interpreter
shutdown/module globals interactions that have plagued a number of
stdlib systems that keep global state.
