While normally not able to pour water out of a boot with instructions on the heel, on Wed, Dec 10, 2003 at 02:41 our dear friend Mike Silbersack uttered this load of codswallop:

Systems such as the Irix I used before moving the servers to FBSD around 1996 - reserverd swap space for applications when the application started up so those needed large swap space. Often it was never used, but the design allocated it anyway.
