[Ecls-list] Closing BSD-SOCKET when a stream has been created

[Goffioul Michael]

If I'm right, the socket is not closed properly on (socket-close...)
when a stream has been created. The reason is that the code relies
on the fact that closing the stream should close the socket as well,
but this is not the case as the stream is a two-way stream and in ECL
the components of a two-way stream are not closed automatically.
