--------------------------------------------
I'm +1, [~lhofhansl] do you want this in 0.94 also?
> TestHLogSplit fails when it sets a KV size to be negative

> It seems to me that we're reading a negative length which we use to create
> the byte array and since it's not an IOE we don't treat it as a corrupted
> log. I'm surprised that not a single build has failed like this in the past 3
> years.
