(EE) SIGIO not blocked at xf86eqEnqueue

Dear all,

I implemented an application with Python and Tkinter. To test it on  
XO, I installed tkinter, PIL, and PMW modules there. However, when  
running it on XO, the following error appeared after the application  
icon disappeared.

(EE) SIGIO not blocked at xf86eqEnqueue
(EE) SIGIO not blocked at xf86eqEnqueue
(EE) SIGIO not blocked at xf86eqEnqueue

Could you kindly let me know how to deal with this error?

Thanks,

Sung-Hyuck
