I agree, I should have made sure my code still compiled after deleting
that one parameter.  And I knew, as soon as I sent the mail, that I'd get
a response like this.  Ten years of Usenet makes one good at predicting
human nature :)

Yes, I did not realize that server functions always need to be exported. I
see now that spawm() always returns a pid even when the arguments are
nonsensical:  spawn(mud, mud, []).  But everything works fine now and I'm
happily writing concurrent code.

All the best,
