The fixes are structured as fixing the code, and then for both
self-documentation & testing turning on:

    TEST_PASSES_SANITIZE_LEAK=true

In the same commit, I could fix the leaks and have a second series later
for turning on the regression test, or just turning on the test and
having it kick in once it's merged with ab/sanitize-leak-ci, but waiting
until ab/sanitize-leak-ci hit master first seemed less confusing for
everyone.

But if you'd like to have 'em now with either of those caveats...

[Just for anyone reading along, I've since pulled the trigger on that
proposed plan at

Some of your colleagues at Google have been running such a review for
what I understand to have been a while, and have recently started
inviting external people. I attended one & applaud the effort.

I think we could run a similar thing here on-list if there's interest
(I'd participate). Perhaps just:

 1. Include a list of un-loved topics in What's Cooking (or someone
    could do it as a follow-up)
 2. Pick N, and distill it down to one, either asa BDFL decision or via
    some easy voting mechanism, like https://doodle.com or E-Mail replies.
 3. Send out a call for reviews with a re-send some time (a week?) later.

If you're not up for organizing it with everything you've got on your
plate I'd be up for doing it. I'd basically just:

 1. Read What's Cooking, subjectively note topics that seem to need love.
 2. Pick one for next week's on-list review club. Via the BFDL-decreed
    methof of "shuf | head -n 1" or similar.
 3. Send out weekly REVIEW CLUB E-Mail with a link to the relevant
    series (if active), or have it be a --cover-letter with a full
    re-send if it's been dead on-list for long enough for nobody to be
    bothered by two parallel threads as a result.

What do you & others think?
