Interesting.  So do you have any idea how long it might be before
anything like this, or the VM would be ready for use.  Even if it only
worked in limited case to start with, or even if we had to write
"scheme assembly" in the beginning, that might be sufficient, and then
we could help improve things as needed.

I'm just trying to figure out what we (in gnucash) should do for both
the short term and the long term (which might be different answers)
with respect to optimization.
