这段代码有可能死循环

local function send_request(self, data)
local n = #data
local sb = self.__fd:send(data)
if not sb then
closefd(self)
return
end
local unsend = sb + 1
while sb < n do
n = n - sb
local sb = self.__fd:send(v.data:sub(unsend))
if not sb then
closefd(self)
return
end
unsend = unsend + sb
end
end

当网络情况比较差，第一次SEND失败，从第二次SEND开始就会死循环，原因是定义了两个local sb

google了一晚，没搜到结果，还是来麻烦云风大侠了 @cloudwu
