title: How do I use SafeMode with the MongoDB C# driver
body: <p>I found that some methods of the official MongoDB C# driver use <code>SafeMode</code> and return <code>SafeModeResult</code>. What is this <code>SafeMode</code> and how do I use it? It would be great to see some use cases - for example, a use case with the <code>RemoveAll</code> method of a <code>MongoCollection</code>.</p>
