+            events, such as 'read completed'. wxMSW has only one message loop
+            for the main thread. If Initialize is called in a secondary thread,
+            the socket window will be created for the secondary thread, but
+            since there is no message loop on this thread, it will never
+            receive events and all socket operations will time out.
+            BTW, the main thread must not be stopped using sleep or block
+            on a semaphore (a bad idea in any case) or socket operations
+            will time out.
+
+            On the Mac side, Initialize() stores a pointer to the CFRunLoop for
+            the main thread. Because secondary threads do not have run loops,
+            adding event notifications to the "Current" loop would have no
+            effect at all, events would never fire.
