Yes, although if I'm doing this for PR, I need to use language which is 
standard in the industry or I won't be understood.  What about 
"high-concurrency pessimistic locking mechanism"?  

I don't have a problem covering this in PR even though it's not really "new":
a) it's never been in our PR before;
b) while it's been available for 4+ versions, who knew about it?
c) we have a new refactored code and cleaned up API
