good idea to just disable keepalive - that made it easier to write a test
there.
> Support WebSockets ping/pong keep-alive in Gremlin server
> ---------------------------------------------------------
>
> Key: TINKERPOP-1726
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1726
> Project: TinkerPop
> Issue Type: Improvement
> Components: server
> Affects Versions: 3.2.5
> Reporter: Andy Davidoff
> Priority: Major
>
> The ping/pong keep-alive system that is part of the WebSockets spec provides
> for successful identification of a dropped connection from either end of the
> connection.
> Currently, the Java client successfully issues keep-alive pings and receives
> pong replies from the server. Unfortunately, the server does not actively
> ping clients, nor does it discover and react to dead clients when keep-alive
> fails.
> This can cause pending client writes to lock up the server indefinitely when
> a client spontaneously disconnects.
