I agree (and have been repeatedly making the point) that we can't do something as drastic as changing the main loop without resolving the I/O thread differences in qemu-kvm. Really, any deep threading changes require that we resolve this which makes this priority #1 for the 0.15 release. But virtio-9p needs a threadlet mechanism to make any forward progress. I don't want to roll out our own so I think we need to pull glib into the build ASAP to enable this. But we should avoid major refactoring of the main loop until the two I/O thread implementations are merged.
