  Log:
  allocGroup(): in the case when we have a block of exactly the right
  size to satisfy the request on the free list, we were forgetting to
  update the free pointer before returning it.  This could lead to a
  (very rare) infinite loop, when each time we allocate a block is
  appears to be already full.
  
  This bug was already fixed on the HEAD as part of the recent
  allocGroup() rewrite.
