This is needed so that:
1. We can support multiple devices in the wire. The device will need
to know how to destroy its child objects.
2. The wire needs to be aware of all objects and their in-flight
callbacks so that it can reject them if the wire is disconnnected.
A future change will handle this.
3. Fix leaks of objects on page teardown. When the page is torn down,
the wire client is destroyed, and we skip calling release() for all
objects since the object holding the proc table was also destroyed.
