I was more meaning top to bottom, although I confess I never looked into the feasibility of just rolling my own thing with rack. I should have clarified what I was looking for, which was an event-based micro web framework.
Event machine is what's underpinning cramp, which is what I went for, and it does the job ok. The problems I had were to do with less than full support from the top to the bottom of the stack (basically the only server I could use was Thin, and there was no way to get anything working with Torquebox that I could find)

So even though it's event-based, if I have 1000 clients long-polling (or SSE'ing, or whatever) that would tie up all my workers? I may have misunderstood what we were getting in Rails 4, then.
Rails is not event-based. An evented systems can have an n:m relation between workers and clients.

Yeah, or I did. As far as i understood, Rails 4 just adds streaming responses: the client starts getting bytes as soon as you start generating them (by calling `response.write` or whatever). That's not evented, that's just writing to the response stream, you can do that in CGI if you want.
