Description:
When 2 processes are backgrounded inside $(...), bash forgets the first
one was a child of the shell.
Repeat-By:
Note this needs to be a script, not cmdline, otherwise $! doesn't work.
$ cat demo
output=$(
true &
pid=$!
true &
sleep 1
wait $pid
)
$ bash demo
demo: line 13: wait: pid 25183 is not a child of this shell
