Does anyone have the time to investigate this?

Thanks,
Alex

I tested same configuration on Mac, but no failure.
Failed test seems to depend on machine state.

    static void slowFun() { Thread.sleep(dur!"msecs"(1)); }
    auto pool1 = new TaskPool();
    auto tSlow = task!slowFun();
    pool1.put(tSlow);
    pool1.finish();
    assert(!tSlow.done);

Calling finish without true argument, finish doesn't wait the task. So the result of tSlow.done depends on the timing.

I don't understand the std.parallelism deeply,
but this failure may occurs on other environments.

The test is wrong, not the implementation of std.parallelism.
 finish(false) doesn't guarantee that the task won't be finished, it just
means that the task *may* not be finished.  IDK how this test made it in
there.  I'll make a pull request to get rid of it.
