- * Name: task_delete
- *
- * Description:
- *   This function causes the currently running task (i.e., the task at the
- *   head of the ready-to-run list) to cease to exist.  This is a part of
- *   the logic used to implement _exit().  The full implementation of _exit()
- *   is architecture-dependent.  This function should never be called from
- *   normal user code, but only from the architecture-specific implementation
- *   of exit.
- *
- * Inputs:
- *   None
- *
- * Return Value:
- *   OK on success; or ERROR on failure
- *
- * Assumeptions:
- *   Interrupts are disabled.
- *
