Re: is Ada dying?

I did one in Ada83 that used tasking. It was a rather limited amount of
tasking consisting of just a set of loops to execute things at various
intervals, but it was a tasking app on a 1750a. We had only very limited
rendesvous just to enable lower priority loops to start and didn't use any
of the more sophisticated techniques for sharing data between threads
(parameter passing, etc) because we couldn't stand the processor overhead.
It wasn't easy and we ended up running at near capacity, so I'd obviously
recommend that faster, bigger processors get used for apps, but IIRC, the
tasking executive overhead was only about 7% of our processor time, so I
wouldn't rule it out as unadvisable.
