Well, he presented benchmark figures with two threads, which is a FIFO system with the new GIL (because when a thread releases the GIL, it ensures that another thread takes it). > We have never had high priority for IO threads in python > (and its not-by-design round robin scheduler on single core cpus) and it > is unclear why that should be required now as a fix. I agree that Dave's situation doesn't seem new to me, although he often presents it as a deficiency of the new GIL only.
