Thanks @milesgranger

[jrbourbeau]

Thanks for the updates @milesgranger! We're now getting

distributed/tests/test_system_monitor.py::test_gil_contention - TypeError: KnockKnock.__new__() got an unexpected keyword argument 'polling_interval_micros'

in CI. My guess is we need to set a pin on the version of gilknocker that gets installed

[jrbourbeau]

Other than the related test failure, this PR looks good

[jrbourbeau]

Thanks @milesgranger -- will merge after CI is done
