This is an impressive set of performance improvements. I was testing and
ran into an issue with this following query. It ran successfully against
`tp32`.
```
graph = TinkerGraph.open()
g = graph.traversal()
g.addV().as("first").repeat(addE("next").to(addV()).inV()).times(5).addE("next").to(select("first"))
java.lang.IllegalStateException: The traversal strategies are complete and
the traversal can no longer be modulated

> Improve performance of mutating traversals
> ------------------------------------------
>
> Key: TINKERPOP-1642
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1642
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.2.4
> Reporter: stephen mallette
> Assignee: stephen mallette
> Priority: Critical
>
> Make an attempt improve performance of mutating traversals. Some general
> goals for this ticket should be to:
> 1. Improve performance parity of structure and process methods for modifying
> the graph - structure is pretty far ahead.
> 2. Improve the speed of large chained mutating traversals - see
> http://stackoverflow.com/q/41926409/1831717
> 3. Determine ways to make these performance improvements in {{gremlin-core}}
> so that they may benefit all {{Graph}} implementations
> 4. Improve the speed of TinkerGraph specifically if possible as it is used
> for subgraphing functions in many cases and ends up being useful regardless
> of the graph implementation ultimately used.
