The global data (GD) and function data (SD)
work as they always have worked. That is the
part I was most anxious to test.

GD is sharable between any python functions.
It always was. It is a memory leak hazard with warnings.

SD is sharable within the same *connection*
only by the same function (name+argtypes).
The scope of SD is kinda weird but is
consistent with its previous behaviour.

(I did rerun those tests on the newly correctly
built versions.)
