The answer is closer to option 1) (please forgive verbosity... I need to fill
space to get this through the news filter...)

The Job Control features are based on Berkely xx.xx (pick your version).  The
C Shell (csh) sends SIGSTOP and SIGCONT.  These Berkely functions are not
available on SysV (AT&T Unix), and most of the other Unixen supported on
i386 boxes.
