There are hooks in 7.0 to support that, though they haven't really been
tested or tuned. I expect it would take some tuning to make that fast
enough.
The major difficulty is probably that it's effectively an ABI change,
and I'm not at all sure we want to do this by default. But that may not
matter for embedded apps, where it seems to be attracting the most
interest.
