This patch doesn't seem to be going anywhere, sadly. Since we're a bit
late in the commitfest and this patch hasn't seen any activity for a
long time, I'll mark it as returned-with-feedback. I hope one or both
versions are resubmitted (with additional fixes?) for the next
commitfest, and that the discussion continues to determine which of the
two approaches is the best.
Thanks.
