New description:

 Or tor fails to work.

 {{{
 2017/09/10 15:29:20 tor: Sep 10 15:29:20.000 [warn] Warning from libevent:
 epoll_wait: Function not implemented
 2017/09/10 15:29:20 tor: Sep 10 15:29:20.000 [err] libevent call with
 epoll (with changelist) failed: Function not implemented [38]
 2017/09/10 15:29:25 tor: Process has no control port, killing
 }}}

 For what it's worth, this doesn't happen on all systems.
