Chromium has a shorter timeout than other WebKit ports (6 seconds on release and 12 on debug). We could mark these tests SLOW in the test_expectations.txt file and that would give them 30/60 seconds respectively. Testing locally, they complete at that point, but fail with a text diff.

Looking at http://test-results.appspot.com/dashboards/flakiness_dashboard.html#group=%40ToT%20-%20webkit.org&tests=svg%2Fdom%2Fviewspec-parser- these tests are slow on all ports. Taking up to 19 seconds on GTK debug and 30 seconds on Lion Release with a high variance.

Is there any way we can make these tests faster? More importantly, why are we running fuzzer tests as part of the layout test suite? I realize that the randomization is deterministic, but this still doesn't seem appropriate in principle for layout testing. We run a fuzzer to find problems and then create dedicated reduced test-cases for those.
