try_read_network doubt

[Tao Hui]

Hi!
    I have a doubt, in memcached-1.2.4 try_read_network(conn *c) funcation,
when read returns -1 and  errno  is not  EWOULDBLOCK or EAGAIN, it returns
0. If it's more suitable to change state to conn_closing and return 1. the
patch is as below:
1928,1934c1928
<             else {
<                               /* otherwise we have a real error, on which
we close the connection */
<                               if (settings.verbose > 0)
<                                       fprintf(stderr, "Failed to read, and
not due to blocking\n");
<                               conn_set_state(c, conn_closing);
<                               return 1;
<                       }
