Checking the reference count, it is 2 at this point. After performing a further operation, the reference count is still 2 and then I delete it.
You also might want to try calling gc.get_referrers(arr) before
deleting it, to check if you have any stray references to the array
still around. (gc.get_referrers isn't guaranteed to detect every
reference, I think, but it will detect many.)
