True enough.  But to clarify, we're not talking about those people;
we're talking about *developers* updating xen-unstable bits on an
otherwise completely stable base distro.  And we're talking about
xen-users installing xen-unstable on their systems to see if
it fixes a bug or adds an important feature they are waiting for.
"Oops, networking is broke, I guess I'd better roll back"...
which means fewer people testing and giving feedback on xen-unstable.

Historically in Xen, "song and dance" has been more like
"hum a bar offkey and quickly twirl around" :-)  I hope
this change at this release is a bit more.
