 Description   

In between when sharding is enabled and the first chunks are created, it's possible for another thread on the same mongos to detect the collection as sharded but with no chunks.

Explicitly fixed in 2.1.2.

See DBConfig::CollectionInfo::shard(). Other race conditions on collection sharding remain, however.
