I checked all the related files one by one. :-) I found thst the CPU 100% usage's cause is fontconfig. In my system, the fontconfig is 2.11.1. I reverted this to 2.10.2's fontconfig, then problem has disappeared! I wonder if the 2.11.1's fontconfig has got a bug? Maybe not. But waht's the matter, I wonder.
