1. Run http tests, that force the http server to be spawed. In my case I used http/tests/webgl/1.0.2/resources/webgl_test_files/conformance/textures/tex-image-and-sub-image-2d-with-video-rgba5551.html in parallel 100 times.
2. Before it ends, press Ctrl+C to shut down the testing.
3. Goto 1. It will fail as the server could not be spawned.
In case WebKitBuild/GTK/Release/layout-test-results/error_log.txt mentions "Error: (17)File exists: unable to create scoreboard"
the workaround is to manually remove stale SHM segments:
I suppose we could automate this though.
I think that clean up should be implemented before launching the server.
