I'm not sure what you're after here? Strategy is to make the locks per-zone, per-node, to not take them too long, to not take them too frequently, to do as much *needed* work as possible for a single acquisition of the lock and to not do unnecessary work while holding it - and that includes not servicing ethernet interrupts.
Not having to bump page counts when moving pages from the LRU into a private list would be nice.
The strategy for fixing the double-free race is to wait until you buy an IDE disk ;)
