See: http://buildbot.mongodb.org:8081/builders/Linux%2064-bit%20v8/builds/2931/steps/test_3/logs/stdio The results not returned in the first cursor batch are deleted by the cleanup immediately before the error. |

New test that shows cursor growth after a number of migrations. Migrate alone does not cause this. |

Test case should reproduce. What is required is a long query, but also one that does not return all results in the first batch, the data not returned in this batch is what is deleted. |
