[$] Python subinterpreters and free-threading

At
PyCon 2024 in Pittsburgh,
Pennsylvania, Anthony Shaw looked at the various kinds of parallelism
available to Python programs. There have been two major developments on
the parallel-execution front over the last few years, with the effort to
provide subinterpreters, each with its own
global interpreter lock (GIL), along with the work to remove the GIL entirely. In the talk, he
explored the two approaches to try to give attendees a sense of how to make
the right choice for their applications.
