Graph cycles, liveness and deadlocks Graph cycles, liveness and deadlocks
------------------------------------ ------------------------------------
By default :class:`FlowGraph` does not allow (or to be precise, its builder does not allow) the creation of cycles. Cycles in bounded flow graphs need special considerations to avoid potential deadlocks and other liveness issues.
The reason for this is that cycles need special considerations to avoid potential deadlocks and other liveness issues.
