+* In grading scripts, warn when a fault is caused by an attempt to
+  write to the kernel text segment.  (Among other things we need to
+  explain that "text" means "code".)
+
 * Reconsider command line arg style--confuses everyone.
 
 * Internal tests.
 
-* Add serial input support.  Also, modify tests to redirect input from
-  /dev/null, to avoid stray keystrokes getting sent into the VM.
-
-* Make pintos script read the serial output and kill the subprocess if
-  it panics (after waiting a few seconds) or triple-faults.  Might
-  want it to be optional, so that interactive users don't get killed.
-
 * Godmar: Introduce memory leak robustness tests - both for the
   well-behaved as well as the mis-behaved case - that tests that the
   kernel handles low-mem conditions well.

-  - Do we check that non-empty directories cannot be removed?

   - Need lots more tests.
 
-  - Add FS persistence test(s).
+  - Detect implementations that represent the cwd as a string, by

+    creating a new directory of the same name and putting some files

   - Godmar: I'm not sure if I mentioned that already, but I passed all
     tests for the filesys project without having implemented inode
