I agree. IMO stabilizing our code is the first priority.  We can
tackle the optimization later (probably after the first version of
RPR gets committed).

Also I think we should add this to the RPR restriction list to be
fair for those who are willing to evaluate/review RPR patches.

- Pushing down a run condition is disabled if DEFINE clause exists.

- Replacing frame options by support functions is disabled if DEFINE
  clause exists.
