A lot of threading issues are also cache related. Forget to properly mark access to shared variables and suddenly every thread /CPU core ends up with its own locally cached version of it.

Yes, but this is such a well understood danger that I've never really been bitten by it in practice.

Along the same lines a lot of GPU programming tutorials warn of inconsistencies between threads and it has never been a problem since I just assume I cannot rely on consistency or order of execution, seeing each thread as separate and independent.
