Just use a serial dispatch queue (or if you need to run pre-10.6 use
an NSOperationQueue with a max concurrent count set to 1) and
dispatch operations to the queue whenever you want.
The operation passed to the queue should write some data to the
socket.

Currently my queue code uses the wait/notifyAll methods in Java to
put
the thread into a wait state (i.e. not actively checking and using
CPU) and to wake it up. The methods look like:
void push (String str)
{
queue.add(str);
notifyAll();
}
String pop ()
{
while (queue.isEmpty())
{
wait();
}
return queue.remove();
}
How do you do the samething in Cocoa/Objective-C?
