      Description

      Currently the dbstats command locks the database in MODE_S, which causes issues with transactions that may hold MODE_IX locks for extended periods of time. Similar to the changes we made for listCollections, we should instead lock the database in MODE_IS and then lock each collection in turn to get stats.
