At 4GB you are less likely to fill it up but you are never GUARANTEED to 
have the space in your swap. The only way that you can get that 
guarantee is to have space somewhere that is permanently set aside for 
hibernate.

To be or not to be, that is the question
                2b || !2b
(0b10)*(0b1100010) || !(0b10)*(0b1100010)
        0b11000100 || !0b11000100
        0b11000100 || 0b00111011
               0b11111111
        255, that is the answer.
