Sync ends the transaction, if you haven't created a transaction block by
executing BEGIN. It seems rather pointless to put more than one Sync
in an outgoing packet anyway. Normally what you'd want is to send
Parse/Bind/Execute/Sync as one packet, because if the Parse or Bind
fails you don't want to try the Execute.
