function timer_resume (name)
  local thread = threads [name]
  if thread then
    threads [name] = nil
    local ok, err = coroutine.resume (thread)
    if not ok then
       ColourNote ("deeppink", "black", "Error raised in timer function (in wait module).")
       ColourNote ("darkorange", "black", debug.traceback (thread))
       error (err)


这是wait.lua第43行到51行的内容，有什么问题么？
