 I integrated latest Tor master on 2018-03-15 into
 [http://github.com/iCepa/Tor.framework/ Tor.framework] resp.
 [http://github.com/mtigas/OnionBrowser OnionBrowser 2]. Shutdown with the
 improved `SIGNAL SHUTDOWN` seems to work just fine.

 When restarting Tor, however, it turns out, that the auth cookie is not
 written to the file system on the second time. First time works, file
 obviously gets deleted on `SHUTDOWN` but is not recreated on second start.

 There is an according log entry the first time:

   [info] init_cookie_authentication: Generated auth cookie file in

 This is **not** appearing on restart.
