Subject: Re: a little puzzling
Resource creation completes when the new resource exits its initialization
code; in version 2 this is the top-level body code.
With the "process...end" bracketing, the "do true" loop is spun off as a
separate process, the body code falls off the end, and the creator proceeds
to its next iteration.
Without the bracketing, process creation never completes because the new
helper resource is still initializing in an infinite loop. The user
resource remains blocked on the creation of the first resource and so it
never creates another.
Another way to make this work is to add a "reply" in helper before entering
the loop.
