It seems to work now, but this leads to a more general Spiffy
problem.

Run spiffy with:

(define-http-resource ("/test") "test html, sort of")

and then access /test in any browser.  You will find (I hope) that
the browser hangs until timeout or until you kill Spiffy; I
certainly do.

Sending a Content-Length header, which define-http-resource doesn't,
solves the problem.

The issue is *probably* that Spiffy does keep-alive connections by
default, and without Content-Length, there's no way to know when the
server is done talking.

I'm not sure that keep-alive by default is the right thing (I mean
I'm genuinely not sure: I don't know much at all about how
keep-alive works), and even if it is, there should be a way to turn
it off, and there doesn't seem to be.
