This is not strictly correct: Python relies on a global interpreter lock
(aka GIL) to protect internal data structures. When code in the Python
process doesn't require access to these data structures, threads can run
outside the influence of the lock and run simultaneously on multiple
CPUs. Python's I/O system (eg file/network I/O) and many Python
extensions do exactly this.
