Why are we even scraping stdout?  If we are using qemu 1.2 or newer,
isn't this information also available from a QMP monitor command?  If
so, we should modify the code to use QMP (which will work regardless of
the change in output in qemu 1.4), and leave the old code for scraping
stdout of qemu 1.1 untouched.

I'm a bit late in reviewing this, since you already pushed, but I'm
inclined to NACK it if we can come up with a better solution using QMP.
