I think this would prevent the flow graph from stopping because it
would block there indefinitely.
For that to work, the condition variables of each message port would
have to be poked by the runtime on shutdown.

That's why I proposed a version of delete_head_blocking with a timeout
so we can handover control from time to time.

(this is from a quick glance at the code, I might have missed some stuff).
