Get runner tests working on Windows
Summary
Runner tests on Windows are not reliable/do not complete. This prevents us from being able to confidently release a Windows container executor.
Steps to reproduce
Run the tests
Actual behavior
First execution runs incompletely; second execution hangs indefinitely
Expected behavior
Tests should successfully complete
Relevant logs and/or screenshots
Paste any relevant logs - please use code blocks (```) to format console output, logs, and code as it's very hard to read otherwise. Please paste both build log and Runner's log.
