What you want could be done with conditionvariables. I'll compose a pseudo-code example, shouldn't be too hard to implement.

One thread has something along the lines of:

while(run)
  compose message
  conditionvariable.lock()
  add message to queue
  conditionvariable.notifyOne()
  conditionvariable.release()

While the other thread has something along these lines

while(threadsafe_do_run())
  while threadsafe_queue_empty()
       conditionvariable.wait()
  msg = queue.pop()
  if msg == "die"
      set_run(false)
  conditionvariable.release()
  send msg

So if you don't get any messages push a die-message. Same thing when all messages have been processed.

do_run() and queue_empty() should check their things thread-safely, use appropriate locks.

wait() returns when notifyOne() is called and then the queue has a msg to send. in most frameworks the conditionvariable already has the lock, you might need to add the lock-statement yourself in .NET.
