 Description   

It would be great if we could manually write lock collections (ie: writes are buffered but not committed) and later manually unlock them. This is especially useful for backuping purposes. The database would still allow reads but writes would simply be delayed.

I am looking to use this feature to perform an EBS snapshot on EC2, but fear taking a snapshot when the database is in an inconsistent state.

MySQL has a similar feature.

Such a feature would allow us to perform backups in a way similar to this:
