Yes, the glib main loop is not going to go anywhere if it cannot be
applied to both qemu and qemu-kvm.
(And, I believe a new main loop is a necessary condition to show that
glib is bringing benefits. It's basically impossible to interface
with external libraries as long as we have our own main loop).
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.
