* swapped in you deserve some resources. We protect the last SAFERSS
* pages against paging and will just swap you out rather than paging you.
* Note that each process has at least UPAGES+CLSIZE pages which are not
* paged anyways (this is currently 8+2=10 pages or 5k bytes), so this
* number just means a swapped in process is given around 25k bytes.
* Just for fun: current memory prices are 4600$ a megabyte on VAX (4/22/81),
* so we loan each swapped in process memory worth 100$, or just admit
* that we don't consider it worthwhile and swap it out to disk which costs
* $30/mb or about $0.75.
* paged anyways, in addition to SAFERSS.
