apache spinning...

I found a few httpd were spinning and tracked it down to again no error
checking of a system function.  In read_client_block() or in the 
procedure callign it we need ot check error returns.

The read_client_block() call in mod_cgi was the guilty part, here is a patch.

            if (len_to_read > HUGE_STRING_LEN) len_to_read = HUGE_STRING_LEN;
            
            len_read = read_client_block (r, argsbuffer, len_to_read);
+           if (len_read == 0)
+               break;
            fwrite (argsbuffer, 1, len_read, script_out);
            remaining -= len_read;
        }
