It would be my preference to release with the Cog VM using the naive
SimpleStackBasedCogit code generator.  After all that's worth at least 3x
over the standard VM whereas the unstable StackToregisterMappingCogit is
only ~ 8% faster than SimpleStackBasedCogit.  It's quite easy for me to
generate either; the two coexist in the same VMMaker.
