      Since SERVER-32638, global and database locks can be interrupted when an OperationContext is killed and throw a DBException with an Interrupted error code. This includes all AutoGet helpers.

      The following places in the query code have temporary UninterruptibleLockGuard s to prevent crashing due to inadequate exception handling:
