Off topic

Since I assume that you are a Swede to you should know that we did
"hardware context swithching" for 40 years ago, I would guess that we
actually invented it and it did util recently(few month ago) control all
Civil Aviation in Sweden

And the OS run was OS-2! which was made by ENEA now doing OSE which is
in many many mobiles and all /// systems.

Today "hardware context swithching" is done by moving the OS scheduler
into hardware, thats fast!

The name of these super "first of its kind"? Realtime CPUs was Censor
9103,9107,9109(still in full operation in Civil Aviation in countries)
made by DATASAAB and later /// SAABTECH Sweden.
