I see. I will let other decides on how to deal with this. In dssp2 i
have:

       (call sys.unix_dgram_socket_sendto (client_subj_type_attribute))
       (call sys.unix_stream_socket_connectto (client_subj_type_attribute))

Not sure why i also added the "unix_stream_socket connectto;", but i suppose
there was a need for it at some point at least.
