[erlang-questions] How to manage blocking accept for many sockets?

The problem I have with this model is that it becomes unwieldy to manage a large set of listeners.
I am building a TCP port forwarding concentrator which listens on thousands of IP addresses. It seems I need a process per listening socket unless I use async_accept.

To follow from Constantin's original question: is there a clean way for me to manage (ie. add and remove) a large number of TCP listeners?

Internally erlang can make use of epoll-like syscalls. The asynchronous nature of epoll fits well with the erlang messaging model. Is there an interface which exposes this style of IO to the erlang programmer; ie. many (listening and connected) sockets managed through one object?
