Is there any risks to change the uv_run mode to UV_RUN_NOWAIT in pumpMessageLoop?

I want to run node on Android.

Code first:
```
Thread nodeThread = new Thread() {
@Override
public void run() {
...
while (true) {
Runnable r = mQueue.poll();
if (r != null) {
r.run();
}
mNode.handleMessage();
}
}
};
```
I start a thread for the node loop.
And the runnable offered to the mQueue is like:
```
mNode.getRuntime().executeVoidScript(script);//eg. when java want to callback to js
```
But the mNode.handleMessage() may block the runnable.

So I have to do this as the following：
com_eclipsesource_v8_V8Impl.cpp : pumpMessageLoop
`rt->running = uv_run(rt->uvLoop, UV_RUN_ONCE);`
change to
`rt->running = uv_run(rt->uvLoop, UV_RUN_NOWAIT);`

It just works fine till now. But I 'am not sure.
