I'd hate to see a new event queue interface that people then can't really use due to it not fulfilling their needs, or can't use for some other reason. We've had a fair number of kernel interfaces that ended up not being used all that much, but had one or two minor users and ended up being nasty long-term maintenance issues.. I don't want this to become yet another such one. Linus
