Test passed in Linux 64, which was consistently failing. Will leave open and observe if it occurs again. |

I'm taking the balancer out of the equation here by pre-splitting the empty collection and moving one of the chunks of. The insertion and further splitting should not cause any imbalance. I'm also cranking the comment level to 2 so to get more info, just in case. |

Happened again. I think the current issue is a race condition between the balancer and the script. If the balancer starts a moveChunk, then the script tries as well and correctly fails. |

In observation. Several related fixes were done. |
