>Description:
	System hangs or reboots without panic while performing bulk
	updates of pf tables, eg. while starting spamd-setup, which runs:

	pfctl -q -t spamd -T replace -f -

>How-To-Repeat:
	Repetable in 70% cases of running spamd-setup, either from
	rc scripts or cron.
>Fix:
	Dunno, might be related to:

	http://cvs.openbsd.org/cgi-bin/query-pr-wrapper?full=yes&numbers=4186

	I was getting this also while updating tables.
