I think a destructor is too risky here.
Can't you just register with valgrind a pointer known not to be freed at exit?
Would be nice to have something like __libc_freeres for libstdc++ too, that
valgrind/mtrace/LeakSanitizer could invoke.
I'm afraid tons of programs just do busy work in various threads until some
thread exits the whole app, and your change could break it.
