      Thanks jordi.serra-torrens@mongodb.com for reporting this.

      On v6.0, the ScopedRangeDeleter lock is held while executing the range deletion for a collection C. This lock takes this RESOURCE_MUTEX in MODE_X.

      This can lead to stalling concurrent migrations on collection C here, or here, or here until the range deletion task ends.
