Would it be better to use `QThreadStorage<bool>` (to record if the thread has been seeded) instead of a `QSet`? It would allow us to more easily adopt C++11's `thread_local` once we remove support for older compilers. I also looked into whether we could adopt the higher-quality RNGs that should be available in C++11, but getting them seeded is apparently very difficult to do without introducing errors. Also, I'd recommend using `quintptr` instead of `intptr_t` in the reinterpret_cast, as that seems more accurate for the semantics of XOR. The shift to XOR is a great idea though.
