-// cSocketThreads.h

-// Interfaces to the cSocketThreads class representing the heart of MCS's client networking.
-// This object takes care of network communication, groups sockets into threads and uses as little threads as possible for full read / write support
-// For more detail, see http://forum.mc-server.org/showthread.php?tid=327

-/*
-Additional details:
-When a client is terminating a connection:
-- they call the StopReading() method to disable callbacks for the incoming data
-- they call the Write() method to queue any outstanding outgoing data
-- they call the QueueClose() method to queue the socket to close after outgoing data has been sent.
-When a socket slot is marked as having no callback, it is kept alive until its outgoing data queue is empty and its m_ShouldClose flag is set.
-This means that the socket can be written to several times before finally closing it via QueueClose()
