I checked into my "CosmicCleric" branch the changes I described
above. I've been using this changed code, and the lagging has
diminished, but still exists.
For what its worth, the lagging seems to be a problem once there is
more than ten members in a raid.
Its still a problem, but a little bit less of one.
BTW, a new version of PerfectRaid is out, and I have been using that
one.
