What scenario are you seeing the migration problem in?

We are seeing issues when you change the affinity of an executing thread and
the new affinity does not include the processor it is executing on. Similarly,
we sometimes want to migrate a thread to another processor to get a higher
priority set of threads on the set of cores. We had started to get the issue
characterized and I was going to email this morning when I saw this problem.

What do you mean by generation count? Would this be an atomic
increment/decrement?
