This was a result of my attempt to perform these actions without locking the bridge.</pre>

Since the framehook callback is not called from the bridging core the bridge is not locked, but needs to be before calling bridge_start. The addition to the given patch adds in the necessary bridge locking in order to avoid a deadlock.</pre>
