allow re-targetting of surfaces
Surfaces can now be parcelized and sent to remote
processes. When a surface crosses a process
boundary, it looses its connection with the
current process and gets attached to the new one.

- * - buffers must be locked in the same order they've been dequeued
- * - buffers must be enqueued in the same order they've been locked
- * - dequeue() is not reentrant
