a header included via semaphore.h on FreeBSD.
Umgh. How.. disgusting... :(
Here's the code in question.

Hi,
I'm using KVM win7(32bit) guest, and found that, guest cpu was almostly
60% when it's idle.
The host is centos6.3, with qemu-1.5.1.
In the guest, I found that:

We resort to gcc builtins. If gcc supports C11 memory model, __atomic_*
