Change subject: IMPALA-5199: prevent hang on empty row batch exchange
......................................................................


Patch Set 2:

Yeah I think there are some fundamental problems with the current parallel startup logic -
I don't think it's actually possible to make all cases work with the current approach where
all state is receiver-side and there's no additional communication (point-to-point or via
the coordinator) to disambiguate hangs and delays.
