The pollForIndex method starts a goroutine to check the latest index periodically. But when the HTTP request finishs, the loop is still there and the goroutine never exits. This leads to a memory leak and goroutine leak after each request to the "/wait/:index" API. The problem can be reproduced by ```ab -c 10 -t 30 http://127.0.0.1:8086/wait/1```. After several times of benchmark you'll find that the memory usage grows markedly. Signed-off-by: Shijiang Wei <mountkin@gmail.com>
