  * Count allocations more accurately
  The allocation stats (+RTS -s etc.) used to count the slop at the end
  of each nursery block (except the last) as allocated space, now we
  count the allocated words accurately.  This should make allocation
  figures more predictable, too.
  
  This has the side effect of reducing the apparent allocations by a
  small amount (~1%), so remember to take this into account when looking
  at nofib results.
