I'm afraid this cure is probably worse than the disease, because
now the backend's exiting is held hostage by whether the client
closes its socket (and the resulting FIN reaches us, which it
might not if there's a network problem).
It might be safe to do the shutdown() only, since Microsoft
specifies that that doesn't block, but I have no idea if that
would improve matters.
