[C/R][PATCH] Use __WALL option in waitpid()

[Sukadev Bhattiprolu <sukadev-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>]

The coordinator creates the children with clone(), so pass the __WALL
option to waitpid(). Otherwise the waitpid() will fail, and bring the
container down even as the application is restarting successfully :-)
