[racket] simple http server without stateful/stateless continuations stuff

In Racket 5.3.4, is there a way to use the barebones HTTP-serving 
functionality of the Racket Web Server code, without getting any of the 
``Stateful'' or ``Stateless'' stuff, nor any trickiness that it does 
with the callback code to support the continuations?

I just want each request to result in a callback in a new thread that 
lets me get header values and read POST data, and then write the 
response headers and content to a port.)

I see the documentation in 
"http://docs.racket-lang.org/web-server-internal/dispatch-server-unit.html", 
which looks like it might have things I can use (unclear), but it 
appears to be some documentation on private internals, not public API.

(This is for some unit testing of clients for various webservices, in 
which I need to emulate the interfaces of the webservices, and to have 
the tests be able to see both client and server sides.  For this 
purpose, I really don't want the "web-server" trickiness with the code, 
and I need a public API.)
