The name of swap_out is historical. It currently does no writing to
disk it just removes the page from the page tables. But the page is
still in RAM. The other routines are what decide which page should
actually be reused, or which pages get written.
The current code is both simple, auto-tuning and does a fairly good
job so look very closely at it before trying to randomly tune it.
