title: .NET system-wide EventWaitHandle name allowed characters
body: <p>I'm just curious off hand, are there any restrictions on the naming of a system-wide <code>EventWaitHandle</code>? I want to use a URL as the name for one, but it could have a great deal of odd characters, I don't want it to silently fail or some other such, so just checking up on here if there are any known illegal characters for the names of these.</p>
  
  <p>I tried finding this myself, but my google-fu wasn't up to snuff.</p>
