Xen 4.0 Feature Freeze Announcement

From Keir in xen-devel:
Lots of new features have recently made it into the xen-unstable tree, and I think now is the time to declare a freeze so that we can get 4.0 out the door early in the New Year. If you’re sitting on any feature patches, declare them or send them on now – I want to freeze the tree except for any agreed special cases at the end of the week.
