Hmm, we put a lot of work and time into this solution. While I acknowledge this is a difficult area, so are many others in hotspot which we are not shy of changing. And we did not change the coding on a whim - the proposed solution IMHO is better than the assortment of piled-on hotfixes we had before and dissolves quite a bit of complexity. That makes the code easier to understand and maintain in the long run. @caoman also provided a regression test, so that's covered too.

But if you have concrete misgivings about the proposed solution, let's discuss it.
