Re: [Maxima-discuss] Multiple copies of maxima in one Lisp process

[Matthias K. <mk...@uc...>]

Michel,
Thanks a lot for sharing this. I'm open to using multiple threads in
ECL for my use case, but haven't checked the details about its thread
support yet.

I understand that the special variables defined in MAXIMA have
thread-local bindings, making the bindings of these variables separate
while running in separate threads. But I don't think it will help with
global state such as assumptions or the gensym counter, unless I am
missing something.

(By the way, in your version of the code, why do you have to go
through the print representation (WRITE-STRING, MREAD-RAW) at all?
Don't the threads share the same heap and can directly communicate
using values?)
