This sounds like a good idea to me, yes. And maybe we could also ease
the situation a little bit by providing the first stable .1 release
already two or three weeks after the .0 release [*] ? Then these "we are
not 100% sure whether this is a severe blocker or not" patches could
simply be provided to the public with that .1 release instead of
blocking the QEMU master branch in freeze state...

[*] I know that means more additional work for Michael - sorry for that
... but at least we should talk about this, I think. Maybe someone else
could also help with the releases if it's too much work for one person?
