CPython is more that "a particular implementation" of python, and the
GIL is more than an "artifact".  It is a central tenet of threaded
python programming.

I don't advocate relying on the GIL to manage shared data when
threading, but 1) it is useful for the reasons I mention 2) the OP's
question was almost certainly about an application written for  and run
on CPython.
