This looks interesting, eagerly looking forward to learning what IPC will look like compared to python multiprocessing, Golang goroutines, C++ threads, and Java threads.
I wish there were a way to do away with the GIL entirely ^^.
https://github.com/colesbury/nogil does manage to get rid of the GIL, but it's not certain to make it into Python core. The main problem is the amount of existing libraries that depend on the existence of the GIL without realizing it - breaking those would be extremely disruptive.
