Update for changed return values.

Loop in order to make sure all objects are really drained. Objects may become undrained as other objects become drained (e.g. a bus-bridge has a packet, while a bus is empty, and the first drain() will cause the bus-bridge to give the packet to the bus).
The only case we know every object is actually drained is if they all return immediately that they are drained.
