The original bug report comes from simply bootup: "I'm loading all the firewall rules during boot-up and this 6 secs slowness is really not very nice to wait for." IOW, the problematic case likely effectively has _nothing_ else going on. Sure, there might be some parallelism (the bootup scripts are getting better for that), but hopefully not 6 seconds worth, and not likely any complex critical sections.
