// On other linuxes and darwin, the `read` call gets an ECONNRESET in
// that case. On sunos, the `write` call fails with EPIPE.

// However, old CentOS will occasionally send an EOF instead of a
// ECONNRESET or EPIPE when the client has been destroyed abruptly.
//
// Make sure we don't keep trying to write or read more in that case.
