  11 Bug-Description:
  12
  13 There are some cases where the shell reaped a background (asynchronous) job
  14 and would incorrectly try to set the terminal's process group back to the
  15 shell's. In these cases it never set the terminal process group to that
  16 jobs's process group initially, so resetting it is incorrect.
