What was the reason for using a density scanner then throwing GPUs at it, rather than just using a scanner that worked, such as 13C MRI ?

Keep the GIL and avoid the problems its removal will cause. Allow parts of your program to run in a separate namespace with explicit passing of objects. No sharing means no contention, so no overhead.

Is it really too late to not do this ? The only reason to get rid of the GIL is to help threading, but that's not a thing we should be doing. Threads need to just die, and be replaced by something less idiotic. Seriously, having the CPU run fragments of your program at random, so that all the previously ordered pieces are now contending with each other and even themselves? How can anyone not see that this is the stupidest idea in the world ?
