Hi Stefan,
I was bisecting qemu-kvm.git.

This seems strange to me.
What commit 12d4536f7 did was to switch to a threading model in
*qemu.git* that is similar to what *qemu-kvm.git* has been doing all
along.
That means the qemu-kvm binaries already use the iothread model. The
only explanation I have is that your bisect went down a qemu.git path
and you therefore tripped over this - but in practice it should not
account for a difference between qemu-kvm 0.14.1 and 1.0.
Can you please confirm that you are bisecting qemu-kvm.git and not qemu.git?
Stefan
