Allocated memory that's paged out and not used is nearly irrelevant (I believe this is true even though a 200mb JVM heap will likely see some unnecessary rotation in/out due to GC - ideally you'd manually configure the heap appropriately (smaller) if you intended to challenge total system memory w/ many processes).
