Our merge logic seemed to ignore the singleton optimization, and just watched the length of the
times
member, presuming that it would grow in proportion to the number of updates produced. That .. used to be true. But with the optimizationtimes
doesn't need to grow at all, if all updates have the same times. This is common in a snapshot, for example. This seems to have the potential to be very disruptive when such a merge happens.
