Chapter 5 Runtime

Rename this chapter. I don’t know what to call it.

5.1 Execution Model

Execution model - what gets run at plumb() and run() time.

Not sure if this really belongs here, but not sure where else to put it if not a new chapter.

5.2 Managing State

 - In-memory Environments and <<-. BAD, STATELESS
 - Cookies
 - Concurrent programming (if multiple proc's)
