      Description

      If a CSV read has a HEADER and has very few records (< header lines) on each slaves, then if only some slaves start, it might cause a deadlock.

      This is really a CSV bug, it's currently trying to handshake between slaves in start() and should delay the header processing until needed.
      The bug was exposed by this change: https://track.hpccsystems.com/browse/HPCC-17991
