That depends on the state of the socket during resume. If the
suspend/resume is quick enough, then the socket may still be connected,
or if we're using UDP then we might just get the reply and carry on
successfully. Otherwise, the call will eventually time out, or will be
cancelled when the kernel finds that the socket has been closed.

Either way, this should do the right thing.
