In the critical section of a migration we check to make sure a majority of secondaries have received the migration writes. If the secondaries fall behind at that point, it's possible for the migration to be stuck in the critical section for a long time (we timeout after 5 minutes). During that time, however, the whole cluster can become unusable as setShardVersion commands will block until the shard is out of the critical section.
