In 777, tasking was not allowed. Each "task" is written as a main
procedure, and proprietary hardware/software is used to
schedule the tasks, gauranteeing that a each task will complete in its
allotted time, or have the processor forcibly taken
away from it. I don't know if this design was a Boeing decision or not.
