Hey -- very good questions. This article was a broad overview, and I wanted to get across the fundamental "physics" of concurrency more than specific solutions.

Hey -- very good questions. This article was a broad overview, and I wanted to get across the fundamental "physics" of concurrency more than specific solutions. Where I talked about solutions it was to illustrate how those principles operate. I'm also not actually that knowledgeable about concurrency so I didn't want to say anything stupid. :D I'm more journalist than expert. I've gotten many responses like yours, though. This subject probably deserves another round of research and a follow-on article or two. Thanks!
