In Python, everything is a Dictionary.

Linux should not be in the loop for critical systems. The software that takes the input from the throttle control and determines the proper fuel pump rate should be written directly for the microcontroller hardware. For the system that receives ground radio data and renders radar info to the dash panel, that can be running Linux.

Most multi-threaded software was OS-specific, so they just used the OS threading utilities directly. Most serious multi-platform software writes their own abstraction on top of threads anyway.
