PS13, Line 130: opened = true;
> we want to call close() and fail() on startOfPipeline, even if open fails?
right now, this is the protocol. we have to follow it since all operators are 
implemented with this assumption.

If we want to change it to make it only call close if open succeed, then we 
need to re-visit implementation of all operators.
