That has nothing to do with specialty engines.  As a matter of fact it makes
the problem worse due to all the engine switching that has to take place. 
Not to mention that the specialty engines could be in a different book.  So in
that respect, the entire concept of specialty engines is bad and was done for
marketing / pricing.  It never had anything to do with helping performance 
and mixing traditional and new workloads on the same LPAR.
