Thanks Pavel, this hack works.
..
Freeing memory... ^Hdone (0 pages freed)
Freeing memory... ^H-^Hdone (4636 pages freed)
Freeing memory... ^Hdone (0 pages freed)
Freeing memory... ^H-^Hdone (914 pages freed)
Freeing memory... ^Hdone (0 pages freed)
Freezing CPUs (at 0)...ok
Any mm guru know how to fix this?
