That seems like a thing worth trying. Thank you for the suggestion.
Python on VxWorks (or QNX) was - and is - my primary approach, but Python on
Linux might be possible.

What concerned me most was how Python's virtual machine can adapt to a Real
Time situation. I now have got some enlightenment on that.

Regarding the application I have in mind: it's not avionics, just to test
avionics.

Thank you all
