I wasn't offended. Anyone who uses Ada in a heavily C domain like GUI
work needs a much thicker skin than that. I was just advocating removing
a gaudy variable.

Ahhh, you've already done that then. It looks like I'm going to end up
owing you that virtual beer. :-(

finding out what OS mechanisms it uses to accomplish tasking (since you
said elsewhere it isn't using OS threads). There ought to be some clues
to that in your compiler docs.
