failing specs under ng-pipeline

[colinsurprenant]

This spec fail is intermittent and I cannot reproduce it systematically. I have to run the specs a few times to trigger it. @andrewvc this error seems to indicate out-or-order batches since the Expected 6249, but got 6374 difference is exactly 125, the default batch size.

Using Accessor#strict_set for specs
Run options: exclude {:redis=>true, :socket=>true, :performance=>true, :couchdb=>true, :elasticsearch=>true, :elasticsearch_secure=>true, :export_cypher=>true, :integration=>true, :windows=>true}
