BTW: Some years ago we discussed the idea of pluggable VMs for

We could then have a VM based on byte code using a stack

and perhaps one that uses the Stackless approach.
What is the usecase for having pluggable VMs?
Running an application full time on multiple machines
Is the idea that, at runtime, the user would select which virtual

From you comments below, I would presume the selection should be at
startup, from the command line, before building Python objects.
How would the user make that determination intelligently?
The same way people would determine whether to select JIT or not -- by
testing space and time performance for their app, with test time
proportioned to expected run time.
