Understand that that is just a "slow-mode" test that will revert to not
working before the weekend is over when I take out those comments. We do
not have a solution to this. I might be able to report it, but I think we
just have to hope that this gets fixed in the next Safari release. I cannot
imagine a small example that reproduces it. We tried this on three
different Macs, and only one had the problem (and two had the same 7.0
Safari). I think we just have to write off that particular version of
Safari.
