In the end the node reaches synchronization, message processing loop starts and releases all of these waiting goroutines, but it's better for us to avoid this happening at all. This also makes double-starting a no-op which is a nice property.

In the end the node reaches synchronization, message processing loop starts and releases all of these waiting goroutines, but it's better for us to avoid this happening at all. This also makes double-starting a no-op which is a nice property.
