title: Log4Net: Enumerating GlobalContext properties?
body: <p>I'm trying to utilize the Loggly appender utility for log4net. <br/>
  I've found that their code is enumerating through the <code>ThreadContext</code> properties and appending them to the payload getting sent over the wire to the loggly service. Good idea! However, the same feature is not being applied to the <code>GlobalContext</code> properties. Figuring this was a miss on their part I tried my hand at enumerating through the <code>GlobalContext</code> properties and adding these to the payload as well.<br/></p>
  
  <p>However, this has proven to be a problem. There doesn't appear to be any way to access the keys and associated values as the <code>ThreadContext</code> properties are accessed.<br/></p>
  
  <p>How can the <code>GlobalContext</code> properties be enumerated? </p>
