+* Code:
+
+ - 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.
+
+ - Need to check the wait system call more thoroughly.
+
+ - Library is not precisely standard, e.g. ptrdiff_t should not be
+ defined by stdlib.h.
