in thread IO::Select and sockets

Any servers that handles mutliple connections must

  • Wait to read incomming connections from the server socket.
  • Wait to read incomming requests from each client socket from which a request hasn't been obtained.
  • Wait to write reponses to each client socket from which a request has been obtained.
  • Wait for errors.

All of these can occur at the same time, which is why can_* are insufficient, and select is desired on the server side.
