For clean qemu stop (or shutdown in guest), we could use qmp-events
https://projects.honeynet.org/svn/sebek/virtualization/qebek/trunk/QMP/qmp-events.txt

But this need some kind of daemon/proxy which is always connected to qmp sockets (we can have only 1 connection by qmp socket),
which can catch async events messages
and then send qmp commands through this proxy.

Seem to be more easy to implement (and should work with SIGKILLed)

>>there was no obvious stop signal one could listen to... 

same here :(
