Subject: [PATCH 06/33] Close stdin/out/err before listening for incoming
 connections.

When running vsftpd as a stand-alone FTP daemon, vsftpd
did not close stdin/out/err. This caused the start script
to hang waiting for stdin to close. Before this patch was
applied, one had to hit ctrl+c in order to get shell prompt
back. Correct behavior:
$ /etc/init.d/vsftpd start | tee
Starting vsftpd for vsftpd:                                [  OK  ]
