This is a very old revision.

We have several related bugs, often with proposed solutions. Someone needs to rework the proposed solutions into a form that can be landed into the tree, see <http://webkit.org/coding/contributing.html>.

Here are the bugs I could quickly find (I'm also listing Sparc and Alpha issues here, as they may have common root causes).
