  The init() command initializes the task queue and scheduler data
  structures. runNextTask() MUST run to completion whatever task the
! scheduler's policy decides is the next one. If there are no tasks
! to execute, runNextTask() MAY put the CPU to sleep.
  
  The TaskBasic interface is this:

  |  ``interface SchedulerRun {``
  |    ``command void init();``
! |    ``command bool runNextTask(bool sleep);``
  |  ``}``
  
  The init() command initializes the task queue and scheduler data
  structures. runNextTask() MUST run to completion whatever task the
! scheduler's policy decides is the next one: the return value indicates
! whether it ran a task. The bool parameter sleep indicates what the
! scheduler should do if there are no tasks to execute. If sleep is
! FALSE, then the command will return immediately with FALSE as a return
! value. If sleep is TRUE, then the command will not return until a task
! is executed, and SHOULD put the CPU to sleep until a new task arrives.
! Calls of runNextTask(FALSE) may return TRUE or FALSE; calls of
! runNextTask(TRUE) always return TRUE.
