The bug I was aware about was fixed. Can you remind me if there's
another one I'm not aware about?

The fix only affected mmapped chunks and the realloc comment was for
heap-managed chunks, so unfortunately I don't think it helps.

That code also involves a tradeoff (sacrificing a little time for the
sake of reducing fragmentation), so it's not 100% clear that it's even
desirable. I'd at least like to wait til some time other than
right-before-release to study the issue.
