Returns true iff dtls is empty (no locks are currently held) and we can add the node to the currently held locks w/o changing the global state. This o

Add cur_node to the set of locks held currently by dtls.

Returns true if there is a cycle in the graph after this lock event. Ideally should be called before the lock is acquired so that we can report a dead
