Yes, perhaps. I've had good experience with these when it comes to
avoid leakages when releasing resources, particularly for resources
allocated by external libraries (cough, OpenSSL, cough). And there
was some work to make these more scalable, for example.
At this stage of the CF, it seems pretty clear to me that this should
be pushed to v17, so moved to next CF.
