Example.lua script exits and doesn't wait for callbacks

[stephenlam]

I'm new to luvit so I'm not sure if this is the fault of luvit or of luvit-redis. When I run luvit on example.lua, I don't get any output. I only get output if I set up a server that is listening on a port, by adding the lines below:

-- Load the http library
local HTTP = require("http")

-- Create a simple nodeJS style hello-world server
HTTP.createServer(function (req, res)
  local body = "Hello World\n"
  res:writeHead(200, {
    ["Content-Type"] = "text/plain",
    ["Content-Length"] = #body
  })
  res:finish(body)
end):listen(8080)

I think this may be happening because luvit exits before the redis.print callbacks have a chance to fire.

I'm on OSX 10.8.4 / luvit 0.6.1 (brew) / latest luvit-redis (04f1fe8bd0968764be7b2f2fb7b53781686ec630).
