Undo hack to overrun test

This commit broke the overrun test:  05c8f85

This hack fixed it:  e3237db

After the 'autoload' feature, 05c8f85 was reversed:  164647d

Now the overrun test is breaking on the buildbots, even though not on
my various test environments.

This commit reverses 05c8 because it's right, and hopefully the
buildbots will stop getting hosed on this test.
