I'm of the same opinion. As far as it comes to recommending a mitigation technique when TCP and the OS runs out of memory resources I think we can do better than merely looking at connections in persist state. As others have pointed out there is also the case of a connection which makes very slow progress (and uses up a fair bit of send buffer space). Ideally one don't want to penalize connections that happen to be over slow links, so some care would be needed.
