Details:

Use case: A gui with two buttons.   One button has an action method which
calls setState: on the other button with the value NSOnState.

Procedure:
1) Run the application attached.
2) click the button 

RESULT: None of the radio buttons in the matrix are highlighted.
EXPECTED: The second button from the top should be highlighted.

Procedure 2:
1) Load in the debugger
2) set a break point in buttonhit: method.
3) run the application attached in the debugger
4) hit the button, it should stop at the breakpoint
5) continue in the debugger console.

RESULT: The radio button which should have been highlighted in the previous
case is now highlighted.
EXPECTED: This is what was expected, except it should have happened in the
first case without the debugger breakpoint.

Does this issue indicate a race condition of some sort?  Given that GUI is
single threaded I'm not sure what's going on here.
