Sometimes the answers are pretty…

A couple things happened to prompt me to do this: the non-GIL version is able to beat the GIL-version performance with 2 threads, and profiling is showing that any further work will be fairly involved. I’ve been experimenting with a prototype…

Lately, I’ve been thinking a bit about supporting parallelism in Pyston — this has been on my “wish list” for a long time. The state of parallelism in CPython is a bit of a sore subject, since the GIL (“global interpreter lock”) essentially enforces single-threaded execution. It should be noted that a GIL is not…
