Two general issues with dropping the global mutex like this:

This is true for qemu-kvm only, right?
Nope, this applies to both implementations.
Oops.
qemu-kvm specific patches which add the cpu_single_env tracking (not
polished yet) are here:
http://cgit.freedesktop.org/spice/qemu/log/?h=spice.kvm.v28
Cannot spot that quickly: In which way are they specific to qemu-kvm?
cpu_single_env bookeeping. But if upstream needs that too having
specific patches is pretty pointless. I'll go fix it up upstream then.
cheers,
