[Tinyos-help] How a event can post a task???

[Frederic Beaulieu]

I'm just looking in the scheduler task loop and I wonder how an event generated 
by an interrupt can post a task if the while loop waiting for a task is in 
atomic section (see code below)??? It seems very strange.

  command void Scheduler.taskLoop()
  {
    for (;;)
    {
      uint8_t nextTask;

      atomic
      {
      while ((nextTask = popTask()) == NO_TASK)
      {
        call McuSleep.sleep();
      }
      }
      signal TaskBasic.runTask[nextTask]();
    }
  }
