  o Removed code:
    - We no longer maintain an internal freelist in memarea.c. Allocators
      should be good enough to make this code unnecessary, and it's doubtful
      that it ever had any performance benefit.
Remove the freelist from memarea.c This is in accordance with our usual policy against freelists, now that working allocators are everywhere. It should also make memarea.c's coverage higher. I also doubt that this code ever helped performance. 2016-02-24 20:32:09 +01:00			`o Removed code:`
