close > clean on Windows 10 leave cluster log files behind

[bunchrt]

I see we're doing the right calls:
runner.close();
runner.clean();

so, I have to go in and occasionally blow out a ton of dead es-cluster dirs. clearly, something is holding the logs open.

versions this is observed: 7.8.0, 7.16.3.

thoughts?

...the logs of the test instance shown below.
