Hello Group, I'm writing a simple chat client-server as an introductory example, and now I'm wondering about some things. First: Do I have to make TCPSocket#puts TCPSocket#gets thread save by using mutexes? Second: Is there a possibility do use push rather than poll for reading the Socket. (If it is already threadsafe, then there is nothing to do here, but if not, I'd have to peek the TCPSocket, and send afterwards if nothing was in the pipe). Otherwise I could just have a reading and a sending thread. Thank you, Brian
