Resolves #2715. On Windows, listening on stderr was keeping the test-proxy process alive and it wasn't shutting down after all tests completed. There may be a better solution using PTY, but stock support in std or okio for PTY isn't adequate in Windows and this narrow use case doesn't currently warrant the amount of effort I put into heaths/akv-cli-rs to fix a similar problem.
