  Log:
  Optimize arena_bin_pop() to reduce the number of separator operations.
  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.
