Sharding 10 (02/19/16)
There are cases where the donor shard can abort the migration without contacting the recipient shard. If it starts another migration before the recipient shard realizes it, then it can call _cloneMigrate against the donor shard and interfere with the new migration. A similar issue exist for _transferMods as well.
