This testing is great stuff. It would be cool to have a buildbot
(http://buildbot.net) and run this regularly. Ideally test-tools would be part
of ladspa/lv2 sdk and the plugin-packages add running the test tools as part of
make check. Bonus points for rerunning tests on success under valgrind memcheck
once again.
