It is worth noting that support for non-PTYs for -monitor only came
along in QEMU >= 0.9.0. Thus this patch entails droppping support
for QEMU 0.8.1 which we had previously supported.

IMHO, QEMU 0.8.1 is ancient[1] enough now, that this is not something
to worry about. It might be worth explicitly adding a check to the
function where we detect QEMU command line version to reject any
QEMU < 0.9.0 just to avoid surprises.

ACK

[1] Fedora Core 6 was last to include that version IIRC
