I'm developing on 10.4 and have already implemented my thread using mach
ports as your first link shows, this is how my client sends the msgs to my
server thread.


However, my client is blocking when the msgs are sent to the server unless I
use the protocol modifiers (like oneway) on the thread, which then give me a
different problem.
