That stands to reason.  Unless the name db is in the module scope of the
close function, you won't find it.  Why not just pass the db object into the
close method and simply delete the cursor object?  I normally use many
cursors per db connection.  It's not obvious that you'd want to delete them
at the same time anyway.

I've never closed a cursor object explicitly.  Failing to close it doesn't
create a memory leak, with or without gc enabled.
