+* The tests in tests/ don't apply the grading patches.
+
+* We need better and more example programs.
+
+  - Need an mmap example program as a replacement for the crappy mmap FAQ
+    question.
+
+* Make it clear that the students own their code, because there was some
+  confusion on that point.
+
+* Threads:
+
+  - join-invalid doesn't compile if tid_t is not scalar type.
+
+  - mlfqs tests suck.  They aren't even correct, e.g. the amarv
+    submission from win0405 is graded incorrectly.

+  - Don't emphasize that stuff needs to be copied from user space to
+    kernel space.  Instead, emphasize validation and suggest that
+    copying is a common solution and that it will be necessary in
+    project 3 and in real OSes.  Also revise the grading criteria to
+    match.

   - Move `join' implementation here, from `threads' project, to help
     normalize the project difficulties.

+* VM project:
+
+  - Discuss the perils of mixing dirty bits between kernel and user virtual
+    memory.
+
+  - Sample solution.
+
+  - Update grading/vm to reflect new mmap, munmap forms.
+
+* Filesys project:
+
+  - Increase maximum disk size from 8 MB to something that actually
+    requires doubly indirect nodes.  There is a negative pressure here
+    from the bitmap object--perhaps we need a specialized bitmap that
+    doesn't have to be all in-memory at once.
+
+    Alternatively, shrink the inode size.
+
+  - Add mkdir and ls example user programs.
+
+  - Add option to disable buffer cache.
+
+  - Get rid of "dump" commands--they're not really useful.
+
+  - Sample solution.
