43  * access the graph as long the writer is not modifying the graph.
93  * currently running the graph.
105  * Start an exclusive write operation to modify the graph. This means we are
106  * adding or removing an edge or a node in the block layer graph. Nobody else
107  * is allowed to access the graph.
112  * main loop is allowed to modify the graph.
127  * Read the bs graph. This usually means traversing all nodes in
128  * the graph, therefore it can't happen while another thread is
132  * the graph, therefore wait in a coroutine queue.
