I've used Hunchentoot (weitz.de/hunchentoot) in production with strong track record.
antiweb (hoytech.com/antiweb) also looks promising, but I haven't put anything into production with it yet.

Hunchentoot's builtin multiplexer is one thread per connection, or one process for all incoming connections: you can customize the taskmaster to be event driven, but then, you will have to write your own load-balancing cruft code to distribute load between processes; something you get for free with a proxy.
