+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

 care to avoid unwanted reentrance.
 

+The {\bf wxSOCKET\_REUSEADDR} flag controls the use of the SO\_REUSEADDR standard
+setsockopt() flag. This flag allows the socket to bind to a port that is already in use.
+This is mostly used on UNIX-based systems to allow rapid starting and stopping of a server - 
+otherwise you may have to wait several minutes for the port to become available.
+This option can have suprising platform dependent behavior, check the documentation for
+your platforms implementation of setsockopt().
