Hi, could you people, who know more about the VM than I do, have a look at my following blog post and tell me if I'm in the right or some things should be amended ? I'm talking about the global interpreter lock in the vm and thread source (1.9.2-p0): http://jabberwocky.eu/2010/10/02/where-is-the-global-interpreter-lock-/ (constructive comments, are very welcome and will be properly attributed, of course) Thank you, Elise
