Non-standard copyright format — company name and author are concatenated.
Use one or the other: either "Red Hat, Inc." or "Michael Menasherov
<mmenashe@redhat.com>". Same issue in patches 2–4.

after SAFE_KILL to ensure the child has exited and its result is collected
before cleanup() runs.

Patches 3/4 and 4/4 look good.
