* Reintroduced for Proxy 4.0.
*
* We can't reliably detect whether a peer has disconnected, but we can
* detect one situation that occurs commonly in Proxy: if sn->csd polls
* ready for reading but there's no data available to be read, the user
* probably got tired of waiting for a slow origin server.
*
* There are numerous caveats. Here are a few:
*
* 1. if the client did a shutdown(s, SHUT_WR), we'll mistakenly assume
* that it disconnected
* 2. if the client sent a pipelined request before it disconnected, we'll
* never notice it's gone
* 3. if the client's network connection died, TCP can take a long time (up
* to and including forever) to notice
*
* Note that the underlying fd may be O_NONBLOCK or ~O_NONBLOCK, but we
* must always avoid blocking.
