Reduction showing bug in patch

The attachment contains two JavaScript files that demonstrate a bug in this
patch.  Running "testkjs foo.js foo.js" with the patch applied gives the
output:
--> undefined
--> 151
OK.

Without the patch it gives:
--> 202
--> 201
OK.

The numbers are timing-related so the different values are expected.  What is
incorrect is "undefined" being displayed in the first instance.
