-------------------------------------------------------------------
* sleeping less than 1ms inevitably ends in failure
* properties() is not a contributing factor
* failure is independent of transaction rate
* -once ~200k vertices are added, it does not appear to ever fail, regardless
of sleep-
* once the server has handled ~200k addV() requests, it does not appear to fail
ever again, regardless of sleep
* when there is failure, or no resultant vertex, the server logs:
{noformat}

> Affects Versions: 3.2.2
> Reporter: Robert Dale
> Priority: Critical
> Labels: console, groovy, neo4j, python
>
> I could reproduce on remote neo4j, but not embedded, nor remote TinkerGraph.
> server:

> console:
> ./bin/gremlin.sh
> gremlin> graph = EmptyGraph.instance()
> ==>emptygraph[empty]
> gremlin> g = graph.traversal().withRemote('conf/remote-graph.properties')
> ==>graphtraversalsource[emptygraph[empty], standard]
> gremlin> for (n in 0..10000)
> { x = g.addV('block').property('hash',
> '1234').property('txt','text').id().next(); g.V(x).id().next(); }
> java.util.NoSuchElementException
