Alright, I've committed this with an updated note regarding the locking,
and a few additional regression tests (which appear to have upset some
of the buildfarm- will look at that...).
Please let me know if you see any issues. I'm planning to spend
more-or-less all of tomorrow looking over the RLS patch. As it's rather
large, I'm not sure I'll be able to get through it all, but I'm gonna
give it a go.
Thanks,
Stephen
