    Apparently. Sendmail() expects to see EWOULDBLOCK even though the
    socket has not been set to non-blocking. The kernel returns ETIMEDOUT
    if no resources are presently available. I know what my Sun does
    under these conditions, but I don't think a kernel crash is the
    correct response either!
