[Ngie Cooper]

Author: ngie

New Revision: 323348
URL: https://svnweb.freebsd.org/changeset/base/323348

Log:
  Unbreak :broken_pipe
  
  - Capture exit code in pipeline and test in output.
  - Drop awk use in favor of `sleep 2`. This helps guarantee the EPIPE
    behavior without the potential race.
