it's both. That is, job control is needed in the kernel and the shell
has to know what to do when you type ^Z or fg or bg, etc. ksh supports
job control ONLY WHEN the underlying operating system does. If you take
a vanilla bourne shell and compile it on a system with job control,
you won't get a shell with job control support.
