Regarding the first patch: The actual hard work of removing the lock was
done by Oscar, but I have set myself as author for fear of saying
something stupid in the commit message that would then be attributed to
him...  Not sure what the best practice is there, please feel free to
reset the authorhip to him (or I can send a v2) if that's preferred.
