FWIW, I was surprised to hear that leak sanitizer reported this kind of
leak.  IIRC, valgrind has an option to ignore these, for just the reason
that Mike pointed out -- there's no point to handling a leak just before
exit.

Anyway, I researched a little and came across this answer:

I don't know if that's something we'd want to enshrine in the tree, but
at least now we know there's a way available if we want it.
