- Signal readable when read is closed and writeable when write is closed
- This seems counterintuitive on the surface but signaling the socket in this way ensures that pending reads and writes are cancelled if either side shuts down send/receive
- Graceful close (recv() returns 0 bytes and FD_CLOSE is signaled when we receive a FIN) works much better
