Have the grizzly folks thought of separating the 'intercepting filter' code into
its own little project?
This is a fantastically useful pattern for server writers, which is why grizzly,
netty, mina and others use it. It would be great to remove the networking
specific code and make it available as a separate jar. Contributers could then
write different concurrency strategies, etc.
Grizzly is already very modular, this would just be another module!
