    test: deflake chan/select3.go · a1e7fb4e
    Josh Bleecher Snyder authored
    On a slow or distracted machine, 0.1s is sometimes
    not long enough for a non-blocking function call to complete.
    This causes rare test flakes.
    They can be easily reproduced by reducing the wait time to (say) 100ns.
    
    For non-blocking functions, increase the window from 100ms to 10s.
    Using different windows for block and non-blocking functions,
    allows us to reduce the time for blocking functions.
    The risk here is false negatives, but that risk is low;
    this test is run repeatedly on many fast machines,
    for which 10ms is ample time.
    This reduces the time required to run the test by a factor of 10,
    from ~1s to ~100ms.
    
    Fixes #20299
