Okay, so there is no downgrade for precise since nm was never updated. I seem to be able to reproduce the issue by leaving nm running a long time, like it just happened since nm has been running overnight. This leads credance to the memory leak theory, but still I only have 12m RSS which doesn't seem like that much.
I've recompiled the quantal packages for precise and will see if this fixes the issue. If so, we'll probably have to bisect the change that fixed this problem.
