I should add that it was 1990 that I was doing this, and although some things have improved, I think the overall picture hasn't changed a lot. Threads weren't common back then, and are now, as people realise they need to be able to run things in parallel. The tool I have now allows people to write multi-process programs and have them communicate effectively. I'm still trying to get permission to release the system as open source, or at least publish the ideas, but the industry is notoriously secretive and conservative, so it'll be some time yet.
