Ugh. I actually intended to pull in ps/reftable-write-optim as a
dependency because I know it causes conflicts. But I screwed this up as
I thought that the topic was merged into "master" already, even though
it has only hit "next".

I'll refrain from sending a new version immediately though and will wait
for reviews first. Once those are in I will pull in the above topic.
