Log:
MFC r184459
- Whenever a password/shell is changed via rpc.yppasswdd, the daemon leaves
one zombie process because it does not do the cleanup. For a long running
NIS/YP server, it will have lots of zombie processes on it. Fix that by
ignoring the SIGCHLD signal since we don't really care about the exit
status in this case.
