4.2 signals broken?

[Lepreau at UTAH-20.ARPA]

From:  Jay Lepreau <Lepreau at UTAH-20.ARPA>

We were all clearly warned about the libjobs stuff going away.
Excerpt from 4.1 man page:

SIGSYS(2J)	    UNIX Programmer's Manual	       SIGSYS(2J)

BUGS
     The job control facilities	are not	available in standard
     version 7 UNIX.  These facilities are still under develop-
     ment and may change in future releases of the system as
     better inter-process communication	facilities and support
     for virtual terminals become available.  The options and
     specifications of this facility and the system calls sup-
     porting it	are thus subject to change.
