      Description

      One is in the destructor of the statusHolder:

      https://github.com/mongodb/mongo/blob/r3.1.9/src/mongo/db/s/move_chunk_command.cpp#L83

      and the other is when the critical section finishes:

      https://github.com/mongodb/mongo/blob/r3.1.9/src/mongo/db/s/move_chunk_command.cpp#L511

      This creates a small window where a new migration can start and the destructor will set the state of the migration to not active.
