Maybe this is not really an issue, but (except in certain formal semantics)
it troubles me to think of this infinitely busy behavior as a _single
action_. I think it is quite different from the other actions one considers
in the model, which (when they occur) consume finite (though not
specifically bounded) time (or perhaps can be viewed as occurring in an
instant). Jut expressing some uneasiness. It seems to be to be infinite
_repetition_ of a non-interacting (silent) action ...
