New submission from nvdv:

Unfortunately concurrent.futures.ProcessPoolExecutor does not provide any means 
to interact with worker processes (like initializer function in 
multiprocessing.Pool constructor).

This problem has been mentioned at least once:

It's not hard to work around this issue by subclassing ProcessPoolExecutor and 
adding all necessary methods, but IMO solution can be more generic.
