Plugin tests are remarkably fragile on Windows
There is something odd afoot in the tests in testsuite/tests/plugins on Windows. In any given testsuite run at least half a dozen of these tests fail for one reason or another (often a timeout sometimes another). I'm collecting these failures here to try to make sense of them:

Actual stdout output differs from expected:
