Just to follow up on this with some numbers from an internal thread.
We got a load of 167 (I think operations / second) on lmdb, essentially
the same as the 160 we saw on master. Windows 2012R2 gives 235 on the
same virtual hardware, for reference.
So no massive gain, but no massive loss either. This will likely
change with larger user sets (I don't have the details to hand as to
what the DB size was).
