   thing to note is that memory objects are typically 1MB in size and allocated   
   on 1MB boundaries. So a request for 8GB will get you 8192 1MB memory objects.   
      
   They will be 8192 contiguous blocks.   
      
   As such, there will be a 4 GB boundary that has 4 GB of available memory.
