    Make test_different_fname_concurrency less racy

    This test case makes a bad assumption about when a greenthread will run
    and signal its done event. The test code yields once using a sleep and
    expects that the done event will get signaled before the test code runs
    again. This may not be the case. Instead, yield up to 10 times waiting
    for the done event to occur.

    I was not able to reproduce this failure locally, but we're seeing it
    regularly in CI. It seems that this should resolve it.
