    Traceback (most recent call last):
      File "/srv/slapgrid/slappart9/srv/testnode/bpy/inst/test0-0/parts/slapos.core/slapos/tests/slapgrid.py", line 907, in test_one_failing_daemon_in_service_will_bang_with_watchdog

      File "/srv/slapgrid/slappart9/srv/testnode/bpy/soft/5082e1741ad09c0910ec59bf9feae300/eggs/six-1.11.0-py2.7.egg/six.py", line 673, in assertCountEqual
        return getattr(self, _assertCountEqual)(*args, **kwargs)
    AssertionError: Element counts were not equal:
    First has 1, Second has 0:  'crashed'
    First has 1, Second has 0:  'launched'
    ```
    
    This test uses a service that will create files `launched` and `crashed` files
    when running, and just after telling supervisor to start the service test
    inspects the directory content.
    If service had time to start, then files are created, otherwise they are not.
    
    Change the service to wait for a delay before creating the files to reduce the
    change of race condition here.
