[icecast] 99% cpu usage help

Thanks.

In my rc.icecast script, I put a >/tmp/icecast.out and a
2>/tmp/icecast.err to try and follow your advice.  When I turned it
on, I got alot of "You can run, but you can't hide" lines over and
over in the icecast.out file.  I tracked it down in the code and
found src/admin.c was printing the message.  The function
handle_admin function has a while loop that prints the message which
is llike this.

        while (con->food.admin->alive && thread_alive (mt)) {
                /* con->sock will be STDOUT, so special case reading
to use STDIN */
                if (fd_read_line_nb(fileno(stdin), line, BUFSIZE))
                        handle_admin_command (con, line, ice_strlen
(line));
                else
                        fd_write_line (con->sock, "You can run, but
you can't hide!");

        }

I added a system ("sleep 5"); before the fd_write_line... function
call and it brought my CPU percentage down to nothing.

Keep in mind that I AM NOT A C PROGRAMMER.  I don't know what this
function does and I'm sure there are 20 ways I could've done this
better.  I'm sure I screwed something up but I can still stream audio
and my CPU is not dying now.  (Maybe the admin stuff doesn't work??)
This may be better suited for the development thread but, oh well.
