Hmm, I'm not sure how to rewrite the test using the `inject()` approach.
The following snippet shows no performance issues at all:
```
strategies = new DefaultTraversalStrategies()
strategies.addStrategies(SackStrategy.build().initialValue({1}).create())
t = __.inject((1..8192).toArray()).barrier(); []
t.asAdmin().setStrategies(strategies)
t.asAdmin().applyStrategies()
t.iterate()
```
> Improve hashcode and equals for Traverser implementations
