 wxSocketBase is the base class for all socket-related objects, and it
 defines all basic IO functionality.
 
+Note: (Workaround for implementation limitation for wxWidgets up to 2.5.x)
+If you want to use sockets or derived classes such as wxFTP in a secondary thread,
+call wxSocketBase::Initialize() (undocumented) from the main thread before creating

+wxSOCKET\_REUSEADDR can also be used with socket clients to (re)bind to a particular local port
