[Vm-dev] Multi-core system Squeak (was Re: Sista alternate bytecodes + Java Bytecode ?)

This was my thinking on eLinda, whose combination of evaluating in Linda TupleSpace Subspaces and also the eventual sending based upon Erights.org ELib. I added event registrations of Tuples with ETupleSpace default eventuallyDo: [:tuple | count := count + 1]. Every eval afterwards would count. That eventual reactor runs on the PriorityVat'
s Process. If tuple evals in the subspace started using the Vat's process, then it would be single-threaded, multitasking. I feel it could be a monitor of task dispersal.

Here is the latest eLinda, for Squeak and Pharo: http://www.squeaksource.com/Cryptography/elinda-HenryHouse.3.mcz

I also think it would make a good parsing engine for scripting ai computations. I was looking at PeitiParser and thinking of changing their baskends to generate Scripts that could run through this linda-vat engine.

As you have said, just thinking out loud.
