Own tag might be a goood way forward as the code itself can run on Python 3.7 by avoiding the multiprocessing. It would be purely to state that we don't want to test the mp parts of the code. How do I make an optional tag? I am worried that since this is not simply an optional package to test but against a Python version, it would require a slightly invasive change to the doctesting framework. There also is an option of testing for a more specific import from Python too.
