Dup() save the socket handle in a TWSocket property for later calling 
winsock function.
The function list you give is rather short. Other winsock functions maybe 
called, for example GetSockName, Shutdown, IoctlSocket...
So limiting TWSocket to call only the mentionned function would result in a 
drastically reduced feature list and would need a flag to raise an exception 
if an unallowed function is called. It could work.
