31 *
32 * Test that that isn't true anymore by scheduling two jobs:
33 * - one, as above
34 * - another that runs in 2100ms
35 *
36 * If everything is working properly, the 2100ms one should run first
37 * (and exit the mainloop). If we ever see the 21475 second job run
38 * then we have trouble (since it ran in less than 2 seconds).
39 *
40 * We need a timeout of at least 2 seconds because
41 * g_timeout_add_second can add as much as an additional second of
42 * latency.
