Ok, so how will this impact users on a single machine which is used to
host VNC sessions? I've got machines with 30+ users all running one
or more VNC sessions each on there. Nothing CPU bound generally,
unless something freaks out and starts hogging a CPU. But will the
overhead of 1000 groups be noticeable?

Thanks,
John
