This test runner passes on Lucid amd64, but it is using the oldest combination of the import matrix: python2.6, pygtk, webkit 1.0. The natty users are python2.6, gir, webkit 3.0

natty amd64, python2.6, pygtk, webkit 1.0 also segfaults. the natty amd64 has a JIT issue in both 1.0 and 3.0 libs.

The segefault is caused by repeated calls to start and stop the gtk main_loop in a single python process. WebKit does not like the repeated start and stops in main_loop, maybe because some state is left behind.

The test browser is stable called repeatedly in a subprocess. This is slower than working the browser in proc.
