OK, I only asked because the examples seem to have different return
values for success/failure, and I wanted to be sure that wasn't more
than a programming habit.

You've already implemented your idea so perhaps this is moot, but to
explain my thought: The same widget could get invoked for all
descriptors as long as it has a way to tell which descriptor caused
the call.  Hence my suggestion of putting the descriptor number in
$NUMERIC etc.; the single widget could just do "case $NUMERIC in ..."
or something (such as passing the FD as an argument, which appears to
be what you did).
