Yes - I wanted to check if there is interest in the feature before I commit time to write the patch, documentation, tests, etc. (And also I wanted to check if there's a better way to do it.)

In any case, thanks for picking up on this.

Disown is an admittedly obscure reference to the shell built-in of the same name (https://tinyurl.com/qfn8ao7). The idea is to get the point across that the pool is truly abandoned, and its running futures are left to their own devices. Maybe wait_at_exit would be a clearer name:

    pool.shutdown(wait=False, wait_at_exit=True)
