I'd like to have a few more test cases around global references in
emacs-27, as the current test cases only test some simple/success
cases, and we'd probably want to test at least a few more edge cases
(e.g. freeing global references in a different order than allocating
them). I've added two more test cases on master and will see that I
can add a few more in the coming days.
