    The ProcessPoolExecutor processes start method can only be change by changing the global default context with set_start_method at the beginning of a script. We propose to allow passing a context argument in the constructor to allow more flexible control of the executor.

    Adding this would allow testing ProcessPoolExecutor with all the available context
