msg_layer module blocks when sends fail

[bxatnarf]

The msg_layer module needs some sort of timeout when it fails to send a message. Currently it just blocks and fills the log with "send interrupted" messages.

In deq_send

while (remaining > 0) {
		int sent = ksock_send(sh->sock, p, remaining);
		if (sent < 0) {
			MSGPRINTK("send interrupted, %d\n", sent);
			io_schedule();
			continue;
		}
		p += sent;
		remaining -= sent;
		//printk("Sent %d remaining %d\n", sent, remaining);
}
