Hi all,

I'm reposting Aviv's series partly for visibility, since the previous
versions were buried in a thread, but also to respin patch #1 - Aviv had
fixed up the bugs in my initial draft, but I also get reports against the
original commit on my branch, so I ended up taking a second look, and
deciding the improvement was worthwhile.

Thansk,
Robin.
