Zombie processes in the exec-healthz command #3003

I'm using exec-healthz container to poll google.com using timeout -t1 wget -O/dev/null google.com command. Everything works perfectly except the exit of the timeout leaves behind a zombie process. For details, you can watch this screencast:

Can anyone explain what's happening here?
