I suspect that there is an element of this.
There is also the factor that if Xen was merged into linux, we would
then be able to work towards a sane(r) virtualization layer that would
be useful for KVM, Xen, and possibly others. This provides a technical
benefit to the code base by introducing a more logical organization
rather than having ad-hoc changes sprinkled all over.
