That still doesn't make it any les crap: because any thread that exits
without calling the "magic exit-flag interface" will then silently be
lost, with no information left around anywhere.

The whole interface is bogus.

If you want to do this, you can do it at _clone_ time, by extending on the
notion of "when I die, tell the parent using signal X" and making that
notion be a more generic "when I die, do X", where "X" migh include
updating some parent tables instead of sending a signal.

But the magic "exit_write()" has to die.
