On Qt Release bot it is still flaky.

Ones it timeouts:

http://build.webkit.org/results/Qt%20Linux%20Release/r150050%20%2860096%29/results.html

Other case that it has stderr output 
"FAIL: Timed out waiting for notifyDone to be called"

Skipped on Qt in http://trac.webkit.org/changeset/150576.
Please unskip it with proper fix.

This test is still flakey on Mac.

And a test with a 1.5s timeout is crazy! I have no idea what this test is trying to do. It seemed to be specific to the chromium compositor, so we should just kill it.

It is not specific to the chromium compositor. It was made for the coordinated graphics (EFL, GTK+ and Qt). We were actually surprised to see this case also fail on Mac and Chromium.

Bug 110027 tracks Mac issues with this test, which are not necessarily the same as on other platforms.
