fast/workers/storage/change-version-handle-reuse-sync.html sometimes times out on Windows. See the URL for one example. Here are some others:

http://build.webkit.org/results/Windows%20Release%20(Tests)/r71337%20(6008)/fast/workers/storage/change-version-handle-reuse-sync-pretty-diff.html
http://build.webkit.org/results/Windows%20Debug%20(Tests)/r71336%20(21977)/fast/workers/storage/change-version-handle-reuse-sync-pretty-diff.html
http://build.webkit.org/results/Windows%20Release%20(Tests)/r71335%20(6006)/fast/workers/storage/change-version-handle-reuse-sync-pretty-diff.html

It seems to have started timing out around r71335.

I've added this test to the Windows Skipped file.
