Thank you for the careful reviews - and especially for pointing out when a given pattern does occur elsewhere in the codebase!

As suggested I will skip the additional locations that you've found while reviewing this series - but I'm starting a separate series where I can address those. I have been focused on getting tests to pass leak-free one-by-one, but spotting and fixing patterns is probably more efficient (since author and reviewer already have the right context) and in some cases might fix leaks that aren't occurring during the tests.

ATB,
