What process carries out paging? If paging is preformed by a paging
daemon, then the paging process will still bring the computer to its
knees. sshd would need to have a higher priority than the paging daemon.

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.
