I suspect any particular feature taken on its own always wants the shortest possible development cycle, and that what ends up happening is just that there are a lot of interdepencies and just plain "different" development-cycles. Which is not a bad thing per se, and pretty clearly is unavoidable. So I'm not complaining. It's just a fact of life. I think that the best way to "solve" the problem is to partially ignore it, and I don't think it's a bad thing that we have many different trees, and some of them are less strongly coupled to others - exactly to handle the inevitable case of release cycle lag. For example, I absolutely detest the BSD "world" model, which actually makes these problems bigger by tying different projects together into one tree. I think it's much more important to try to have as much freedom as possible, including very much having separate timetables and development environments. > Hasn't ever, I'm afraid.

You see that as a sorry statement, but I don't think it's a failure. Why _should_ one tree have to try to make everybody happy? We want to try to make it easier to keep the couplings in place by striving for portable infrastructure etc, but we would only be hampered by a philosophy that says "everything has to work in tree X", since that just means that you can't afford to break things. I'd much rather keep the freedom to break stuff, and have many separate trees that break _different_ things, and let them all co-exist in a friendly rivalry. And my tree is just one tree in that forest. So it's not a bug - it's a FEATURE!
