There are a number of very recent memory leak patches, so recently that even 3.12 may not have them, especially if you're not on the latest stable update. If you're running the latest 3.13-r2 or a live-git kernel, you'll have those fixes, but there may be others still in the pipeline, as memory leaks seem to be the focus right now and as I said several have been very recently fixed. If you're running the very latest 3.13 git kernels and are still seeing it, then I expect the devs will be very interested indeed, because that does seem to be one of the major focuses ATM, so might as well get it fixed while it's hot! -- Duncan - List replies preferred.
