      The default key refresh time is 3 months: https://github.com/mongodb/mongo/blob/master/src/mongo/db/keys_collection_manager.cpp#L37

      There's a background thread responsible for refreshing keys. That thread renews its OperationContext on each iteration. However, an iteration (I believe) can sleep for the full three months when newly negotiated keys are set to expire. Holding this OperationContext open can block WT tables from being dropped. Generally speaking, an OperationContext should be short-lived.
