What is the idle state *for*?
One concrete use case could be a test suite that swaps out applications between tests without exiting the entire process. But there are other situations where it's useful. The startup script might need a chance to run mandatory code in-between stop and exit, or a debugger might stop a live server (stop accepting connections), run a debug session, fix the problem, then start up again. > This seems to imply that you need these states to exist for > distinct components in a single process -- which would be a > finer-grained sort of "bus" than has been discussed at this > point, at least as far as I understand it. That's not what I had in mind, but I wouldn't be opposed to it.
