This post speculates on the possibilities and challenges of implementing a multi-threaded Emacs with fine-grained concurrency. It discusses the differences between concurrency and parallelism, and argues for the use of level 3 parallelism for safety and ease of use. The post also explores the requirements for a parallel Emacs implementation and proposes ideas to address the challenges of shared memory, buffer locals, and variable sharing. It concludes by questioning the trade-offs and potential benefits of a multi-threaded Emacs.
