Tandem was one of the exceptions. They at least keep updating NonStop. It's still the best in fault-tolerant systems that I'm aware of. Need to do a new survey in that stuff sometime to see if academics or startups have exceeded it yet.

Thanks for links. Didn't have them.

EDIT: Thanks twice given one of those links may have answered a question kragen had in another thread about why no heap allowed in passive, process pairs. I'm thinking they're stateless whereas the active ones are stateful. Heaps need stateful.
