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