  Log Message:
  -----------
  Cleanup: remove dangling free() on malloc path, and adjust heap allocations such that:

1) Usable size >= requested size
2) Heap data structure at end, not at beginning, of heap (so that user heaps start aligned, and so that we aren't grabbing a whole previous page regardless of requested size).
