      Description

      Testing of Flow Control found that a primary can crash on an InterruptedDueToStepdown DBException when an UninterruptibleLockGuard is in use on a lock acquisition that is gated by Flow Control. Lock acquisitions that are gated by UninterruptibleLockGuards should not be subject to Flow Control. There are very few such acquisitions and all of them are by system operations so this work should be safe to do.
