"The StackInterpreter is an intermediate step after closures and before 
the JIT to ensure steady progress and on-time delivery of a substantially 
faster VM. The essential point, of course, is that a stack organization 
suits the use of native call and return instructions whose use, along with 
in-line cacheing techniques, substantially improve send and return 
performance." -

I would say it's a CogVM without a JIT.
