This isn't specific to Redline, but do take a look at the RoarVM http://soft.vub.ac.be/~smarr/renaissance/ a many core research implementation of the Smalltalk VM that does some very interesting things with non-determinism. Also there are Javascript implementations of Smalltalk that run inside browsers like http://amber-lang.net/ although I haven't had the nerve to actually deploy code to users written in Amber.
