Review Comment:
In integer division, `value / 2 + value / 2` does not equal `value`. You can
see this when value is 3. `3/2` is `1` and `1 + 1` is not `3`. A more obvious
sleep logic is:
```java
time.sleep(requestTimeoutMs - 1);
assertFalse(cache.hasRequestTimedOut(bootstrapNode1,
time.milliseconds()));
// Timeout the request
time.sleep(1);
```
