Umgh. How.. disgusting... :(

Hrm. That double dispatch

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:
1) All the cpu is eat by one task called "system interrupt";
2) The virtio net device and USB Uni

Refcnt's atomic inc/dec ops are frequent and its idiom need no seq_cst
order. So to get better performance, it worth to adopt _relaxed
other than _seq_cst memory model on them.
We resort to gcc builtins. If gcc supports C11 memory model, __atomic_*
buitlins is used, otherwise __sync_* builtins.
