Comment(by andrea):

 Replying to [comment:16 nickm]:
 > Ah, okay.  The channel is closing because we're hibernating.  So it
 marks the or_connection, but tells it to flush.  And then a
 connection_edge_end tells it to queue an END cell while the or_connection
 is marked but flushing and the channel is in state CHANNEL_STATE_CLOSING.

 I think the fix is to not mark the or_connection or close the channel
 right away, but keep track of that until after we queue the END cell.  I'd
 have to have a closer look to know how complex that is.
