Emacs UI usually stop responding when it performs a long task, for example, saving a file remotely. I’d be very convenient if I can use eshell or do something else at the same time.
I guess that people propose many solution. Anyway, I wonder if Emacs has any certain direction for improving multitasking support yet.
Probably the direction will be for more packages to use threads.
They currently don’t run in parallel — they’re just sugar over the existing cooperative multitasking model — but hopefully they’ll get that ability in the future.
Does Emacs have a global interpreter lock similar to Python?
The interpreter is completely single-threaded, so there’s nothing to have a lock over.
