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
Some task may be 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();
         }
    }
