[usocket-devel] socket-listen and socket-accept

Hi usocket people! First, what a great library! Easy to understand and use. However... How does one poll a server socket created with socket-listen to see if there's an incoming connection? I want to run socket-accept in that case but I can't block because my program is busy doing other stuff. I've tried wait-for-input but it always returns the server socket (lispworks & sbcl) despite there not being any pending connection. -Shawn
