Well it doesn't matter because again when I use the GPU memory manager
then everything runs fine. I also use the atomic<> class to compare
pointers:

if (MyObject * p = pointer.exchange(nullptr))
    deallocate(p);

So my code of perfectly thread safe. So even if the search engine search
is meaningless, then I'm telling you directly right now from my short
experience on Windows.

I don't think bugs like that are acceptable and the fix is ultra-easy
anyways. So the costs / benefits is gainful IMHO.
