In general, this happens when bash thinks it's interactive but can't
obtain a handle to the controlling terminal that allows it to manipulate
the controlling terminal's process group. Since that's all job control
really is -- switching the terminal's process group between processes --
bash turns off job control if it's not available.
Other programs that attempt to put the terminal into "raw" mode usually
do it by trying to open "/dev/tty" (always the controlling terminal) and
change its attributes. If that fails, they fall back to line-at-a-time
mode.
