Websites doing this would have to be careful about it: they might become the only website triggering a lot of interrupts randomly, which then makes them easy to identify.

Our countermeasure which triggers interrupts randomly is implemented as a browser extension, the source code for which is available here: https://github.com/jackcook/bigger-fish

I'm not sure I would recommend it for daily use though, I think our tests showed it slowed page load times down by about 10%.
