I disagree - the proposed patch maybe provides a very significant
improvment for a certain workload type(nothing less but nothing more),
but it was posted way after -BETA and I'm not sure we yet understand all
implications of the changes.
We also have to consider that the underlying issues are known problems
for multiple years^releases so I don't think there is a particular rush
to force them into a particular release (as in 9.1).
