At this point, comapring the document I have in hand, I think the
semantics between the two are the same.
Further tests showed that the bug does not seem to be related to
this thread.  It is just application related timing issue.

I believe (without checking document), for RTEMS, the preemptive
scheduler is based on priorities, and highest priority task ready
to run (not pended or delayed) is allocated the CPU, right ?
