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.
