New Revision: 197965
URL: http://svn.freebsd.org/changeset/base/197965

Log:
  Tweaks for sigqueue tests:
  - slightly adjust code for style, sort headers.
  - in sigqtest2, print received signals, to make it easy to see why test
    failed.
  - in sigqtest2, job_control_test(), cover a race by adding sleep after
    child stopped itself to allow for SIGCHLD due to stop and exit to not
    be coalesced.
  
  MFC after:	2 weeks
