Yes I agree. A common pattern for each approach. Having the score's 
thread create fill the stack will enforce a common approach.

Yes and why I want to have a common set of code.

Ok. I have no problem with the capture engine borrowing code from else 
where in RTEMS, so what if I place the stack fill code into the score, 
and split the current stackchk code into parts usable by the capture 
engine ?
