    So it appears that SIG_IGN and SIG_DFL were formalized as part of
    7th Edition Unix.

    This came out in 1979, according to <https://wiki.tuhs.org/doku.php?id=systems:7th_edition>. That was
    nearly 4 years after the 6th edition <https://wiki.tuhs.org/doku.php?id=systems:6th_edition>.

    What happened in-between? The porting effort to the Interdata 8/32 was
    one thing. That would have flushed out a whole bunch of PDP-11-isms
    from the source code and APIs.
