I got confused between test-qht-par and qht-bench. However we already
have this in the test case:

    if (g_test_quick()) {
        g_test_add_func("/qht/parallel/2threads-0%updates-1s", test_2th0u1s);
        g_test_add_func("/qht/parallel/2threads-20%updates-1s", test_2th20u1s);
    } else {
        g_test_add_func("/qht/parallel/2threads-0%updates-5s", test_2th0u5s);
        g_test_add_func("/qht/parallel/2threads-20%updates-5s", test_2th20u5s);
    }

So maybe we should be asking why it isn't limiting itself to 1s?
