[John Arthorne <john@xxxxxxxxxxxxxx>]

How are you creating a derived IFile?  If you have your own domain 
object, I assume you have implemented an IDocumentProvider to map your 
input to an editor document. I suspect if you implement 
IDocumentProvider#mustSaveDocument and canSaveDocument to always return 
false, you'll get the behaviour you're looking for (although I haven't 
tried this).
