-* Code:
+* Put time limits on tests.
 
-  - Speed up disk routines: filling an 8 MB disk takes a long time.
-    (They're only slow because timer_sleep always waits for at least
-    one timer tick.)
+* `make grade'
 
-  - userprog project should mark read-only pages as actually read-only
-    in the page table.  Or, since this was consistently rated as the
-    easiest project by the students, require them to do it.
+* We need better and more example programs.
 
-  - For userprog project, don't provide per-process pagedir
-    implementation but only single-process implementation and require
-    students to implement the separation?  This project was rated as
-    the easiest after all.  Alternately we could just remove the
-    synchronization on pid selection and check that students fix it.
+  - Need an mmap example program as a replacement for the crappy mmap FAQ
+    question.
 
-* Documentation:
+* Give advice on how to use `diff' to find out what has changed
+
+* pintos script doesn't (always?) delete temp disks
+
+* GNU make 3.80 or later is required.
+
+* Finish writing tour.

+
+
+* process_death test needs improvement
+
+* Internal tests.
+
+* Improve automatic interpretation of exception messages.

   - Add "Digging Deeper" sections that describe the nitty-gritty x86
     details for the benefit of those interested.

     . Low-level x86 stuff, like paged page tables.

-  - The semantics of the join system call should change so that it
-    only returns the exit code once.
-
-  - mmap/munmap should use segment IDs like Nachos.  Too hard
-    otherwise.

-  - Add src/testcases/vm, src/testcases/filesys and make it clear to use
