Comment (by simonmar):

 So we have to solve the unloading problem first, right?  Also did you find
 any way to reduce that 5-6% binary size overhead?

 Before bumping the performance thresholds you should check whether they're
 reasonable.  Compare against the unpatched compiler (sometimes it is right
 up against the upper limit anyway).  Increasing allocation by 10% sounds
 like a *lot* for this change.
