Indeed a good question, and something I've wondered about before. My
answer is I don't know. :)
When I did Google it before (some years ago), the most frequent answer

It’s not just a Windows thing. On my FreeBSD system it swaps between CPU
cores too. I see this with any long running process th

On my Linux it does not swap the CP
Everything has a cost. But swapping CPU threads isn't as costly as a fried
CPU. Keeping the CPU cool at all costs is better than having a hotspot on
the die which COULD damage the heat sink.
The computing cost of swapping CPUs is probably close to zero. Your CPU
only has so much on-die memory t

As Torsten said, that is exactly what happens. It is not “just in
theory”, it happens all the time. I see that constantly on my i7 CPU
with long running processes.
As for the cost of moving it bet
