+Summary: No exception thrown when deleting a read only file
+Description of Problem:  
+The mono runtime should throw a exception when trying to delete a 
+read-only file under gnu/linux.  
+Steps to reproduce the problem:  
+1. create a read-only file "tmp.tmp"  
+2. create a file test.cs containing...  
+class fred  
+ static void Main(string [] args)  
+ {  
+  System.IO.File.Delete("tmp.tmp");  
+ }  
+3. compile it  
+4. run the executable produced (test.exe) with mono  
+5. readonly file is deleted without exception  
+6. on a windows machine running the same exe with mono, a exception was  
+Unhandled Exception: System.UnauthorizedAccessException: Access to the  
+path "tmp   
+.tmp" is denied.   
+in <0x001be> System.IO.File:Delete (string)   
+in <0x0000c> fred:Main (string[])  
+Actual Results:  
+read only file is deleted  
+no exception  
+Expected Results:  
+exception thown, the file still there  
+How often does this happen?   
+every time  
+Additional Information:  
+Compiled with mono & the microsoft sdk both tried.  
+It seams that the Windows version of mono throws a exception and the 
+version doesn't. Also the microsoft .Net framework throws a exception.  
+running mono version 1.0.4
