Running a single loop many times will not expose much because that loop
(which is NOT within a Forth colon subroutine) will compile only once.
In my performance benchmarking with tb@ I have put 45 IF-THEN and
IF2-THEN2 control statements that will each compile once and reveal the
difference in compilation speeds.
