That's not new, we've been seeing those for awhile.  I've been
ignoring them on the grounds that (a) if the code actually had such a
problem, valgrind testing would have found it, and (b) the message is
saying in so many words that they're ignoring our code in favor of
somebody's apparently-inaccurate model of said code.
