  SVN rev 215615 on 2010-11-21 10:55:16Z by mckay
  
  xargs can be fooled by exiting children that it did not start, causing
  it to kick off a new command before the previous has finished, resulting
  in corrupted (interleaved) output.  It is also fooled by non-exiting
  children it did not start, failing to exit until all extraneous children
  have exited.
  
  This patch makes xargs keep track of children it starts, ignoring
  pre-existing ones.
