It uses the best mechanism for the platform you are running on ...
win32 uses waitformultipleobjects
most unixes will use poll() because of better performance and  
scalability than select
where poll() is not available or is less efficient than select(), it  
will use select()

That's too big a discussion for an email, but the very short answer  
is that it adds ports to the runloop and handles messages arriving on  
those ports. For more detail you should go to the documentation of  
the classes.

A multithreaded connection is one where the same port is added to the  
runloops of multiple threads.  The thread safety issues make it less  
efficient than single threaded connections.
