The point is that the two-way stream is the only place where the sockets 
streams themselves are referenced. This means that whenever the two-way 
stream is garbage collected, the components will also be marked as 
unreferenced and their associated streams closed. And as far as I can 
tell, closing a FILE stream which was opened via fdopen() will also 
close the file handled that was open with the bsd socket routines.
