Ada's Annex D requires that a ``preemptive scheduling, based on conceptual
priority-ordered ready queues,'' model be supported (see (ARM, D.2.1 ``The Task
Dispatching Model.'')) (ARM, D.2.2 ``The Standard Task Dispatching Policy'')
describes a specific task dispatching policy, FIFO_Within_Priorities.
``Implementations are allowed to define other task dispatching policies, but
need not support more than one such policy per partition.'' Reading D.2.2
carefully (especially (11)) will reveal that Simple-Round-Robin can be achieved
using delay 0.0.
Hope this helps,
Frank
