[issue37276] Incorrect number of running calls in ProcessPoolExecutor

[Andrew Svetlov]

Andrew Svetlov <andrew.svetlov at gmail.com> added the comment:

Adding a new state for "not running and not pending but something in between" is useless, it can make .running() result a little more accurate but doesn't improve the real functionality.

The easy "fix" is documentation updating to point that the value returned by running is an approximation. That's true anyway because the future may change its state between reading self._state and returning a result.
