missing old features for new socket streams

Hi, I'm using the socket stream and it seems to work just great for me, but with the stream_socket functions some original socket features seem lost. Is there any way to work around this? Maybe there is need for a stream_socket_set_option function? I personally bumped into this lack of features when I wanted to set my listen queue length on a socket-stream server. How can this be done? And if this is simply impossible, could anyone tell me what this default new queue length is? Thank you, Ron
