When running the whole test suite on my macbook, I consistently see:

When I run the single test alone, I see the output, but it appears after stdout/stderr are captured, so no error is detected:

The test turns on [verbose=mutex]. It's possible that thread output may not be flushed synchronously when the thread ends, creating a timing problem that foils testing.
