Yes, this works. As you say, a thread inherits parameter values (at the time that the thread is created) from its creating thread, and a UDP socket can be used from multiple threads at once and isn't tied to any particular thread, so using `(conn)` in different threads is fine. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
