        /etc/rc.d/named start never returns. Here's the state of named:

grep named 

A  ^C will kill the /etc/rc.d/named command, but a named process
remains, which doesn't react to kill (kill -9 makes it dissapear though).
ktrace -i output available on request.

>How-To-Repeat:
        echo named=YES >> /etc/rc.conf
        /etc/rc.d/named start
        on a sparc system.
>Fix:
        workaround: build.sh -V NAMED_USE_PTHREADS=no
