I could be misreading the information in "3.2 Usage Considerations", but it 
seemed like the modifications to my program were automatic, but maybe that 
only happens when using #lang web-server or #lang web-server/base ?

Regardless, I'm wondering if maybe I should just use (serve) instead of 
(serve/servlet) since I'll likely be working at that level later anyway. In 
that case, it looks like dispatch-lift:make is the main thing I need to get 
things rolling. As a simple example:

#lang racket
(require web-server/web-server)
(require web-server/http/response-structs)
(require (prefix-in log: web-server/dispatchers/dispatch-log))
(require (prefix-in lift: web-server/dispatchers/dispatch-lift))
(require (prefix-in seq: web-server/dispatchers/dispatch-sequencer))
(require (prefix-in stat: web-server/dispatchers/dispatch-stat))

(define (controller request)
   (λ (op) (write-bytes #"<html><body>Hello, World!</body></html>" op))))

 #:dispatch (seq:make (log:make #:format log:extended-format
                                #:log-path "development.log") ; log request
                      (stat:make) ; print memory usage
                      (lift:make controller))
 #:port 8080)

To be clear, it's not just continuations that I want to avoid, I'd also 
like to avoid the changes that are described in section 3.2 above.
