PubNub keeps the process alive after a history query for some reason, so
trying to print the logs history like:
$ resin logs <uuid>
Will result in the logs being printed correctly, but the process waiting
infinitely without ending.
The workaround consists in forcing `process.exit` to exit the process
with an error code zero.
Caveats:
- This workaround prevents this command to be used programatically.
