Variously available on V7.3-2 and later with a patch, with mainline 
availability V8.4 and later.

This itemcode is missing from page 563 of the current VSI system 
service reference manual.

https://www.vmssoftware.com/docs/VSI_OpenVMS_BaseOS/VSI_SYSTEM_SERVICES_REF_VOLI_10-APR-2019.pdf 


A manual which also has odd sorting around _ characters in system 
services, too.  The underscores are seemingly ignored by the sort.

The similarly-retrofit lki$_locks_nonull is also missing from $getlki.

Prolly some other itemcodes from other simiilar back-porting efforts.
