You must send either Flush or Sync after the Parse to force the backend
to emit its response to Parse. The assumption is that in many cases
you'll be sending Parse as part of a batch of commands, and the backend
should batch its responses to minimize the number of network packets
sent. So you have to tell it where the batch boundaries are --- thus,
Flush or Sync. See the docs concerning the difference between the two.
