  Log:
  o Now when SIG_IGN signal action for SIGCHLD reap zombies
  automatically it is possible wait4(2) returns -1 and sets
  errno = ECHILD if there were forked children.  A user can
  set such signal handler e.g. via ``trap "" 20'', see a PR
  for the test case.  Deal with this case and mark a job as
  JOBDONE.
