Review comment:
Interesting - the tool I've always used didn't produce that nice explain
stuff. I didn't realize that such a thing existed. 👍

> Provide a way for scripts to respect with() specification of timeout

> Key: TINKERPOP-2438
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2438
> Project: TinkerPop
> Issue Type: Improvement
> Components: server
> Affects Versions: 3.4.8
> Reporter: Stephen Mallette
> Assignee: Stephen Mallette
> Priority: Major
> Fix For: 3.5.0, 3.4.9
>
>
> This issue sorta relates to the Gremlin Console but I think it's generally a
> server side problem as it could easily occur with HTTP or just scripts sent
> over web sockets. Folks tend to see all the ways they can set timeouts and
> then mix/match them. It only remains a problem with sending a script as
> {{g.with("evalTimeout",100)}} because the server won't know that this value
> was set until the script is passed to {{eval()}} but by then it's too late
> because we would have already started the timeout countdown. While most
> users wouldn't send that as a bare script submission it's a common mistake in
> the Gremlin Console and similar environments where it is not clear you are
> working with a remote graph.
