Remove the call to remove tokens from the parent. Under heavy load
this appears to cause problems with the system timer resolution. This caused a problem with tokens going into the root throttle as bursts leading to some starvation. Also changed EnqueueOutgoing to always queue a packet if there are already packets in the queue. Ensures consistent ordering of packet sends.
