I think the patches make sense, so they should be added to the next branch at least. My general view about pushing stuff to the master during freezes is that it should only done for bug fixes, and these patches are just optimizations, not bug fixes. However, I also think that a freeze without a release candidate is pointless, and since RC1 isn't out yet, I don't mind pushing these to master. Do as you like. -- Tanu
