No, not beautiful at all


This code prevents generic inspection of process status
Process status is in local variables

It requires full context-switch support
Multiple stacks
Saving and restoring all registers
... even if we implement no preemption

Scheduler structures are opaque

Init time is unclean
A task may be still initializing
             while other tasks are already running




    void random_task(some_arg)
    {
         init_this();
         init_that;

         while (1) {
             work_on_this();
             work_on_that;

             os_wait_next_period();
         }
    }
