>Description:

	/usr/libexec/named-xfer, executed by /usr/sbin/named, re'nice(3)'ing
	itself to 20 priority level instead of wanted 0 (default) level.
	This occurs because respective (to strange :-) code from
	/usr/src/contrib/bind/bin/named-xfer/named-xfer.c, lines 351-355 :

		#ifdef RENICE
			nice(-40);
			nice(20);
			nice(0);
		#endif

	works correctly (= sets 0 priority, see comments near) only for
	process owned by super-user. But named (and named-xfer) now owned by
	bind:bind

>How-To-Repeat:

	Run code mentioned above not under super-user.

>Fix:

	I think, we need to do nothing with priority in the named-xfer.c and
	inherit priority level from named process. This behaviour can be
	achieved by #undef'ing RENICE in the
	/usr/src/contrib/bind/bin/named/named.h
