I don't think anybody said that, and based on my understanding
of Python's threading, I don't see why it would be true.

AFAIK, the threads aren't all locked to a single CPU.  However,
there is a global interpreter lock (a mutex), which somewhat
prevents simultaneous execution of threads when they _are_ on
different CPUs.
