The Leopard test slaves do not give identical results to each other. For example: apple-windows-5: http://build.webkit.org/results/Leopard%20Intel%20Debug%20(Tests)/r81334%20(27699)/results.html apple-windows-6: http://build.webkit.org/results/Leopard%20Intel%20Debug%20(Tests)/r81335%20(27700)/results.html We should figure out why the Leopard bots aren't all giving the same results. (See bug 56535 for some related issues.)
Here's another example: apple-macpro-4: http://build.webkit.org/builders/Leopard%20Intel%20Release%20%28Tests%29/builds/29874 apple-macpro-5: http://build.webkit.org/builders/Leopard%20Intel%20Debug%20%28Tests%29/builds/27697
See bug 56544 and bug 56545 for specific tests that are being skipped due to this issue.

Not relevant any more. Test expectations are already revised.
