  Try to get this test to be more stable:
   * disable gc during the test run because we are spawning objects and there
     was an exception when calling Popen.__del__
   * Always set an alarm handler so the process doesn't exit if the test fails
     (should probably add assertions on the value of hndl_called in more places)
   * Using a negative time causes Linux to treat it as zero, so disable that test.
