-/**
- * SizeOf provides a static method that does its best to return an accurate measure of the total amount of memory used by
- * the virtual machine. This is calculated as the total memory available to the VM minus the actual amount used by it.
- * Before this measurement is taken the garbage collector is run many times until the used memory calculation stabilizes.
- * Generally, this trick works quite well to provide an accurate reading, however, it cannot be relied upon to be totally
- * accurate. It is also quite slow.
