I got it to respect Ctrl-C with this patch, although I am not sure the
semantics are right:
diff --git a/src/worker.c b/src/worker.c
index 99e4297..92ac32a 100644
--- a/src/worker.c
+++ b/src/worker.c

ASSERT(r == 0);
r = uv_loop_close(&worker->loop);
What exactly do you mean by your code being "more of a toy example than a
functioning one"? It seems quite good to me as the basis for a
multi-threaded HTTP server. What would you say is missing here?
