Yes, just a rebase. There is still work to be done per earlier in the
thread.

I do want to follow up and note re palloc/pfree vs malloc/free that the
tracking code (0001-Add-tracking-...) is not tracking palloc/pfree but is
explicitely tracking malloc/free. Not every palloc/pfree call executes the
tracking code, only those where the path followed includes malloc() or
free().  Routine palloc() calls fulfilled from the context's
freelist/emptyblocks/freeblock/etc and pfree() calls not invoking free()
avoid the tracking code.

Thanks,
