If you do not set sk_sndtimeo you will get -ERESTARTSYS if there is a pending signal when you enter sendmsg, which we handle properly. However if you set a timeout for your commands we'll set sk_sndtimeo to that timeout, which means that sendmsg will start returning -EINTR instead of -ERESTARTSYS. Fix this by checking either cases and doing the correct thing.
