I want an easier API function to change the backlog,
although I know I can make it using evhttp_acccept_socket().
For example, something like this patch (see attachment) is good to me.
If evhttp starts supporting evconnlistener, an API to add an addtional evconnlistener might help here.
I'm going to close this; it's pretty easy to do now via evhttp_bind_socket_with_handle and evhttp_bound_socket_get_handle.
