      The range deleter deletes orphan documents by constructing a PlanExecutor with a YIELD_MANUAL yield policy. Because of this, any write conflict errors encountered will be re-thrown, but there is no WriteConflictRetry loop in CollectionRangeDeleter::cleanUpNextRange, causing post-migration orphan cleanup and cleanupOrphaned commands to fail unnecessarily.

      The net effect of this is that more orphans remain on the system.
