From the Thinking Outside The Box dept.:
Also, if the performance gains prove to be as earth-shattering as initial results indicate, there's nothing that says
we*have* to wait until the middle of next year to get this out. We could push to get 9.2 out with fewer other features,
orpossibly even break with tradition and backport this to 9.1 (or perhaps have a fork of 9.1 that we only support until
9.2is out).
Obviously, those options all involve serious time commitments and the community will have to weigh those carefully. And
we'dhave to have very strong evidence of the benefits before even having that discussion, because the discussion itself
willlikely be resource intensive. But the option *is* there, should we decide to pursue it.
This means that "this patch is too important to wait another 12 months" isn't really a valid point: it only has to wait
12months if thats what the community thinks is best; otherwise it could miss 9.1 *and* be out significantly before 12
monthsfrom now.
