+* VM project:
+
+ - Discuss the perils of mixing dirty bits between kernel and user virtual
+ memory.
+
+ - Sample solution.
+
+* 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.
