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

[CM]

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?
