Remove the block of code that tries to use delayed regions in LIFO order, since from a policy perspective, it conflicts with LRU caching of newly coalesced regions in arena_undelay(). There are numerous policy alternatives, and it isn't readily obvious which (if any) is superior; this change at least has the virtue of being consistent with policy. END
