There is no way to disable cycle prevention; the GNU Radio scheduler
algorithm requires streaming ports to be a directed acyclic graph.

However, this applies to streaming ports only.  It's possible (though
probably lower in performance) for you to encapsulate data into async
messages and use message ports connected in an arbitrary topology.
