Bash Version: 3.0
Patch Level: 16
Release Status: release

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
