	Mason (see .sig) has the ability to reorder rules; by using the
mark value, it is able to pull the packet counts from an ipchains listing
and append the counts to the rule files it creates.  It also safely
reorders the rules so that higher count rules migrate toward the top of
the list and lower count rules migrate down, without ever changing the
security of the ruleset (for example, it won't change the order of a DENY
rule and an ACCEPT rule).
	This is why I hope the mark value will continue to be available in
iptables - I need this unique number to match up the output lines in a
firewall listing to the original rules in the rule files.
