Hmm.  Well, I'm not used to even thinking of threads unless I'm doing
some kind of classic parallel processing problem (and I almost never
need to do those!), but I can see how that tactic could do the job
as a solution.

I'll have to think about this and some of the other solutions offered, and
see what "feels right" for what I'd like to do.  (whatever that means!)
Thanks for the ideas.
