This is more like - ask ZE not to clean what it points to when it is
cleaning up the zval, and of course not to allow userland to change it.
I needed a similar thing in mysqlnd and went the route of implementing
it on extension level - doing magic with reference counting. Doing this
means that when the user tries to change the internal buffer pointed by
the zval she performs copy-on-write.
Having ZE support for this will be nice!
