I've also pushed out a tree based on this, which contains my little
fixups that I'd suggest to be folded.  Totally untested and written

Note that while I tried to keep all my changes in separate patches, the
main passthrough patch had conflicts during a rebase, which I had to
fix up, but I tried to touch as little as possible.
