It was a "guts of the OS" problem - something to do with adjusting the behavior of the thread scheduler that distributes threads to run on the different available CPUs.

Once the patch is in place for it, it solves the problem at the system level and so individual applications do not need to do anything extra to avoid that particular problem.
