As far as I can tell, he wants to keep the data in one place and just
pass a pointer around between execution contexts. The apparent issue
with using shared memory segments for this is that he relies on
existing components which have their own allocation preferences. So
although you or I might choose shared memory if writing this stuff
from scratch, he doesn't appear to have this option.

The inquirer hasn't acknowledged my remarks about tinypy, but I know
that if I were considering dropping $40000 and/or 2-3 man-months, I'd
at least have a look at what those people have done and whether
there's any mileage in using it before starting a new, embeddable
implementation of Python from scratch.
