Interesting, about that I made some tests and just realized that in some
cases both mine and the original shell implementation are failing on
forcing the system to go to swap (the tests I made when the test was
firstly implemented did manage to make the machines swap, but in
conditions where the system had a significantly higher initial memory
usage). I will work on a better heuristic to force swap.

Thanks for pointing this out,
