    Vasilij> Thank you. Yes, that is the case, the network process is no longer shut
    Vasilij> down, but the 0-length message isn't picked up. It prints the following:

    Vasilij>     Received string (5): "hello"
    Vasilij>     Received string (5): "world"

    Vasilij> Rather than the expected:

    Vasilij>     Received string (5): "hello"
    Vasilij>     Received string (0): ""
    Vasilij>     Received string (5): "world"

Right. Getting emacs to deliver a zero length string to the UDP
process would be quite a change, one I canʼt get to any time soon.

    >> Does guile deliver the empty message?

    Vasilij> Yes it does.

OK.
