RocksDB deleted, but locks still exist

Currently, if I have a connection open to a RocksDB, even if I delete the entire RocksDB on disk, I still can't create a new RocksDB in the same location due to the `No locks available` error. Is this intended behavior, and if so, is there any way to force close all connections to a RocksDB or any other way to force the release of a lock from some connection that wasn't picked up during garbage collection?
