Thanks!

RE your question: Squeak's scheduler (also written in Smalltalk) would need to be extended with support for multi-threading. Since that requires a significant amount of work, it's probably out of the scope of the project at this point (unless someone is interested to work on this, of course). However, it's already possible to do multi-threading from Smalltalk using some other language like Java. We have some students doing just that with Ruby to parse HTML content in multiple threads.
