this probably should be in the build structure. not magically adding 8 mb 
without the
toolstack knowing, otherwise no toolstack can provide more or less slacks on a
per domain basis. And it make precise memory handling a nightmare, and thus
dynamic memory handling too. in some way this parameter is just like the
shadow_memory one in the hvm build structure.
