Unity not properly flushing file output?

So, i've been trying to get Unity to write to some files and the only time the file actually gets created and written is if I generate a file IO exception. If I don't put in bad code which generates an exception the file never actually gets written to disk even though it appears everything went ok. Anyone know what I'm doing wrong here?

  function SaveToXML(filename : String) {

 var writer : StreamWriter;
 var filepath : String;
 var info : FileInfo;
 
 filename = filename + ".profile";
 filepath = Application.persistentDataPath + "/";
 info = new FileInfo(filepath + filename);
 
 //Delete the old file if it exists
 if ( info.Exists ) {
   info.Delete();
 }

 //Create new file
 writer = File.CreateText(filepath+filename);
 
 //Get Serialized Data and write it
 var data : String = Serialize();
 writer.Write(data);
 writer.Flush();
 
 //Close up shop
 writer.Close();
 writer.Dispose();
 
 if ( info.Exists ) {
     Debug.Log("Verified Existance of file ");
 } else {
     Debug.Log("Not Verified");
             //Lets generate an exception
             info = new FileInfo(Application.persistentDataPath);
             if ( info.isReadOnly) {
                 Debug.Log("This will generate an exception");
             }
 
 }
 
 
 Debug.Log("File written " + filepath + filename);
 

}
