And it doesn't respond anymore to subsequent requests?

This message indicates that the remote connection was closed (perhaps
Spiffy outputs a newline too much). But normally, even though the
thread dies, the server should continue to work as normal. That Ctrl-C
doesn't work isn't entirely clear to me, but happens to me as well.

(BTW, Now I realize that I misunderstood your previous mail. Spiffy
handles the signal, but not http-server, so perhaps adding that
invocation to `set-signal-handler!' in your code might work).
