A friend (ubuntu 17.10, staging debs 0.10.3-rc1) cannot start bitmask because it complains about another twistd server should be running, which is not:

$ ps aux |grep bitm
...    6696  0.0  0.0  15920  1072 pts/0    R+   22:15   0:00 grep bitm

$ bitmask
[+] launching bitmaskd...
Another twistd server is running, PID 1965

This could either be a previously started instance of your application or a
different application entirely. To start a new one, either run it in some other
directory, or use the --pidfile and --logfile parameters to avoid clashes.

ERROR: No authentication token found!

Besides a proper fix, what would be the easy workaround for users experiencing this ?
