Konstantin Belousov 545d312293 When a zombie gets reparented due to the parent exit, send SIGCHLD to 
the reaper.

The traditional reaper init(8) is aware of zombies silently reparented
to it after the parents exit, it loops around waitpid(2) to collect
them.  For other reapers, the silent reparenting is surprising and
collecting zombies requires a thread blocking in waitpid(2) just for
that purpose.  It seems that sending second SIGCHLD is a better
workaround than forcing all reapers to obey the setup.
