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 between cores. I have no clue, but I would
imagine that switching between cores in a single CPU is not that
expensive (the cores are so close together and tightly integrated),
compared to switching between physical CPU’s. I don’t have a multi CPU
system to give actual observations, but that’s my theory. ;-)
