Internals of the VM

Hello,

my name is Michael Lesniak and I am a research associate in the
parallel programming languages group of the university of Kassel. I'd
like to take a deeper look at the (automatic) parallelization of
virtual machines and think that scheme48 code, esp. its virtual
machine, seems to be quite good for this[1].

Do you have any resources beside the papers "A tractable scheme
implementation" and "Pre-Scheme: A Scheme dialect..."?  I've
overlooked and which are good start with? Is chapter five of SICP a
good starting point (even scheme48's VM uses a stack?) (read it a
couple of years ago but forgot most of the details). Any general
suggestions before starting to hack on scheme48's VM?

Best regards and thanks for your help,
  Michael Lesniak
