allocWithZone:
Returns an instance of the NSMachPort class.
Overview
For backward compatibility on Mach, allocWithZone: returns an instance of the NSMachPort class when sent to the NSPort class. Otherwise, it returns an instance of a concrete subclass that can be used for messaging between threads or processes on the local machine, or, in the case of NSSocketPort, between processes on separate machines.
