The FSM suite occasionally gets "Error: drop failed: Lock for drop is taken" when it tries to drop a collection. We already wait 10 minutes at cleanup to get the distributed lock, but we only wait the default 2 seconds everywhere else. We're getting the error occasionally at setup, but also could during any workload that drops a collection. This error began to arise more often after we turned the balancer back on because there is now more contention for the lock.
