- *
- * single.c
- *	  set single locks in the multi-level lock hierarchy
- *
- *	  Sometimes we don't want to set all levels of the multi-level
- *		lock hierarchy at once.  This allows us to set and release
- *		one level at a time.  It's useful in index scans when
- *		you can set an intent lock at the beginning and thereafter
- *		only set page locks.  Tends to speed things up.
