Nah, you assumed too much :) I just forgot to mark this as leak-free and
the topic crossed with my memory-leak-fix topics, so I didn't yet find
the time to fix it.

It does highlight an issue though: I think memory leak checks should be
opt-out rather than opt-in by now. Most of our tests run just fine with
the memory leak checker enabled, and that's also where we want to be
headed. So making tests opt-out would likely raise more eyebrows when
new tests are being added that explicitly opt out.

The only reason I didn't send a patch like this yet is that it would of
course create quite a bit of churn in our tests. I'm not sure whether
that churn is really worth it, or whether we should instead just
continue fixing tests until we can get rid of this marking altogether
because all of our tests pass.
