Hi,

I don't think so. We need somebody to make some last modifications to
the patch though and Christian doesn't seem to have the time atm.
I think the bigger memory (size of the per process page table) and #cpus
(number of pg backends => number of page tables allocated) the more
imporant it gets to implement this. We already can spend gigabytes of
memory on those on big systems.
Greetings,
Andres Freund
