  # CriticalSection
  "A stream-flavoured critical section implementation for isolating access to a stream subgraph"
  
  Events entering a stream graph fenced off by a critical section will cause all other entry points to switch into
  blocking mode, with events received at a given entry point being retained in that entry point's internal buffer,
  and the entry point buffer enqueued for subsequent processing. Each time an event flows through an exit point, the
  next entry point in the queue will be dequeued and its next buffered event emitted into the inner stream graph.
  When no data is buffered at any entry point, the critical section unblocks, allowing direct dispatch of the next
  future data item to arrive, at which point it will switch back into blocking mode. Errors ignore critical section
