I think that will solve, but I also think that will kill NOLOCK
performances due to really increased contention.

At this point I fear we could consider reverting the NOLOCK stuff.
I personally would hate doing so, but it looks like NOLOCK benefits are
outweighed by its issues.

Any other opinion more than welcome!
