Not when the trick of getting high order, returning left over pages
is used. I meant just updating the GFP_COMPOUND code to always
use number of pages instead of order so that it could deal with a compound
where the excess pages are already returned. That is not actually that 
much work (I reimplemented this recently for dma alloc and it's < 20 LOC) 

Of course the full rewrite would be also great, agreed :)
