It would not surprise me if it takes longer than the .26 merge window. You're saying you want to delay an relatively simple and imho relatively mature feature like gbpages after that complicated and risky feature PAT? Please take a look at the patches; they're really not very complicated. That seems to me like against your own principles -- simple stuff first -- that you two harped on so extensively on earlier this thread. For me it would make much more sense to put the gbpages first than to delay them for PAT. I only didn't argue this strongly earlier because PAT was already rushed in (for me quite suprisingly) and I didn't want to argue for dropping it. But now that it is gone again anyways delaying the gbpages for it again would be quite unfortunate from my perspective. -Andi
