But max-heap will only limit the heap if the desired heap size (as 
calculated by the various live ratios) is greater than the max-heap flag. 
If the desired heap size never exceed the max-heap, then you should get 
exactly the same behavior as if you didn't specify a max-heap.

In which case, I don't recall the exact difference between max-heap and 
the RAM calculated by ram-slop.
