best way to share an instance of a class among modules?

I was using self correctly, I think; but I should have said that the
code in the importing module would be within a class, so self there
refers to that class. But that's a side point.
I agree that utilities.shared_cursor is visible within the importing
module. But the problem below remains for me...

But the function in the module is also within a *class* so I don't
think the function does have access to the module's global namespace.
Here's the hierarchy:
-- Module namespace....
---- class namespace (DatabaseAccess is the name of the class)
---- function namespace
This is where the cursor is created. How do I get it
into the module namespace?
