Subscriptions page unusable

I've got rather a large number of thread subscriptions built up over the past year. The Subscriptions page lists every single subscription I have. Quite a while ago, bringing up that page started taking many minutes, making the browser memory usage spike to massive numbers. I can't unsubscribe from threads anymore. Which made me stop posting notes when I move a thread. Not good.
