Timeouts not honored

I'm facing this problem on 1.1.0. I'll upgrade to 1.1.1, but I don't see any commits post 1.1.0 that would have addressed this problem. The request times out significantly later than what the timeout prescribed.

```
08-21 18:00:23.382 2741 2922 D MyCode : HTTP->POST->XXX
08-21 18:02:23.723 2741 2913 E MyCode : HTTP ERR<-120,342ms

```

There was one commit to solve having total request time subtract queue waiting time, but I understand the log above indicates that the request was taken into the queue 1ms after being submitted. I have my own retry policy class (created the simplest possible since I was struggling with this problem):

```java
// https://stackoverflow.com/questions/17094718
httpRequest.setRetryPolicy(new RetryPolicy() {
@Override int getCurrentTimeout() {
return timeoutMS; // this is 30000
}
@Override int getCurrentRetryCount() {
return 0;
}
@Override void retry(VolleyError error) throws VolleyError {
throw error;
}
});

getVolleyQueue().add(httpRequest);
```

It's not consistent either, though the numbers are somewhat suspicious. In one session (consecutive requests), I get, for the same 30s specified timeout:

70,309ms
120,342ms
160,641ms
120,442ms
160,467ms
