available_space(s, true) tries to log the current status, which does, in
7e7c9f
turn, lead to another call to available_space(s, true) and so on and so

7e7c9f
7e7c9f
available_space()
7e7c9f
  server_driver_message()
7e7c9f
    dispatch_message_real()
7e7c9f
      write_to_journal()
7e7c9f
        find_journal()
7e7c9f
          system_journal_open()
7e7c9f
            available_space()
7e7c9f
