Wow, that quote is very interesting. Thanks!
(google found the reference for me. One of them (possibly the original reference others are using) is https://www.kernel.org/doc/gorman/html/understand/understand014.html ) I read it, and it appears that the reference is talking primarily about what the kernel does. I kept searching and couldn’t find any definitive statement that a PROGRAM could request this, however apparently some JVM somewhere can do something with memory that almost requires there be swap to keep the JVM from getting killed by the OOM monster… er, killer… er, task.. er, whatever.

"A significant number of the pages referenced by a process early in its life may only be used for initialisation and then never used again. It is better to swap out those pages and create more disk buffers than leave them resident and unused."
