Re: Threads in emacs implementation

[Richard M. Stallman]

    As I understand it such an implementation would not take advantage of
    the new hardware that supports multi-threading, eg: multi-core x86
    processors.

I am not sure that case is important, or that it would outweigh
the slowness of all variable accesses.

I don't think that Emacs will often have multiple threads actually
trying to run.  If multiple users are typing on one Emacs, only
occasionally will they both run nontrivial commands at once.
