It seems I got confused here because I was testing with my distro version of webkitgtk+ that is a bit old.

I'm also getting "Out of memory" exception with last trunk of WebKitGTK+, and also peaking at 3GB of RAM. And the memory is released after this peak.

So.. same behaviour on WebKitGTK+ than on Safari.

Its with a previous version of WebKitGTK+ (2.14.1) that I get the test to happily run.
