Here at Clodsburger Research, we discovered the mystery values, 147
and 148. Please document them on the man page.
$ PS1='$? $ '
0 $ bash
$ suspend
[3]+ Stopped bash
147 $ sleep 88&
[4] 3913
0 $ fg %sl
sleep 88
^Z
[4]+ Stopped sleep 88
148 $
Mention uses: detecting whether a subshell has exited or suspended, etc.
