[racket] Engineering Tradeoffs of ANF transforms and the Stateless Server

Regarding paging... The only three situations in which I consider paging 
acceptable nowadays on workstations and servers, when a handful of 
dollars buys you a few GB RAM:

1. For resilience in exceptional/emergency situations, when the 
alternative would be an OOM kill or a crash.

2. When an application with massive memory requirements was 
designed/tuned specifically to work well with OS's virtual memory behavior.

3. Cloud and shared-hosting servers that don't care if performance blows.

None of my personal machines even have swap partitions, and I don't 
recall using even half of my RAM.  In this screenshot of lower-right 
corner of my screen, it tells me I'm using 16% of 3GB RAM on this 
workstation that's running Linux, X, XMonad, PostgreSQL server, Apache, 
and several different Racket SCGI servers, in addition to my bloated
