I did have indicator-multiload active. Removing it has stopped the leak from increasing at a rate of 1MiB/s and made my computer usable again. There does still seem to be some sort of leak, but the usage has only reached 63MiB and I've been running for about 3 or 4 hours. (The mem usage when logging in starts at about 23MiB or so...)
I did notice that the problem did not occur when running Classic Gnome, even with indicator-multiload running. Just in Unity...
