socket write(2) after remote shutdown(2) problem ?

Hi,

Is the following behaviour correct on a tcp connection:
        * the server issues a shutdown(sock, RW)
        * the client side socket passes in CLOSE-WAIT state
        * the client issues a write on the socket which succeds.

I expected the last write to fail, since the other side is not
capable any more to receive data. Can someone confirm to me one
of the following:
        1. behaviour is correct and why.
        2. shutdown is buggy.
        3. write is buggy.

Thanks.

Attached are sample codes for the "server" and the "client". Test
was done on latest 2.4 and 2.5 kernels.

Stelian.
