Actually, it was based on real-world experience, although as with many
of the details in such standards the standard specified a slight variant
of what had previously been implemented.  The capsule summary:  BSD job
control is a horrible kludge that never did work right and required
vhangup etc.  HP-UX was based on UNIX System V and when customers wanted
job control some reengineering was necessary in order to make it work in
that environment and also to close several security holes.  POSIX job
control was originally specified along the lines recommended by HP-UX
engineers, but got redesigned during balloting, as did lots of other
stuff.  I think the IEEE balloting procedures suck.
