 When the transient-memory-leak was optimized-away in #63588 it was added
 without an explanatory comment. This leaves the code prone to accidental
 removal by someone coming along and thinking that there is extra work
 being done.

 The optimization should be documented so that there’s a stronger guard
 against accidental and well-intentioned-yet-harmful regression.
