Also, Rails (Labs) is just a huge memory hog.  And as long as we're
running an application that uses Rails, that's never going to change.
Perhaps we configure Redmine's cgroup to have a maximum memory usage,
such that it can't affect the rest of the system?

I only expect ParabolaWeb's memory usage to go up when a bunch of
packages have just been updated.
