Cherry-Pick POLLHUP detection#80
Merged

Conversation
When the peer closes a connection but unread data remains in the receive buffer, recv(MSG_PEEK) returns > 0 and is_connected() incorrectly reports true. Add poll(POLLHUP) check before recv(MSG_PEEK) to detect peer hangup regardless of buffered data.
