-  - 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.

-  - The semantics of the join system call should change so that it

 * Code:
 
-  - Rewrite quick_sort() to use heap sort, for O(1) stack usage.
+  - Make threads test use a program and arguments like the other
+    projects.
+
+  - Revise command-line arguments for sensibility instead of for
+    Nachos compatibility.
+
+  - Get rid of all compile-time flags, e.g. MLFQS should be a runtime
+    command-line option.
+
+  - Need an optimization barrier and an explanation of it in the
+    documentation.
 
-  - Rewrite list_sort() to use merge sort, for O(1) heap usage.
+  - Need to check the wait system call more thoroughly.
 
-  - Make printf() test actually check its results.
+  - Library is not precisely standard, e.g. ptrdiff_t should not be
+    defined by stdlib.h.
