Hi guys!

I am in China and haven't read this thread etc, but regarding improved 
SharedQueue - have you looked at SharedStreams:

http://map.squeak.org/packagebyname/sharedstreams

...the SharedBufferStream in there was much faster for lots of objects 
or characters, since it relied on primitives. In fact, a looooong time 
ago Stephen Pair thought it should have replaced SharedQueue.
