To clarify: two or more threads are simultaneously running PulseAudioSanitizer._unload_pulseaudio_module(), all execute
  $ pactl list short modules

..and all see that the "module-stream-resource" module is loaded, causing them try to unload it. The first unload succeeds, subsequent unloads show the "Failure: No such entity" message.

Easy solution would be to protect the call to _unload_pulseaudio_module and _restore_pulseaudio_module in a multiprocess.Lock(), but this would still mean that we're loading and unloading the module two times per webkitpy test run.

Dominik, do you have any preferred solution? IIRC running failed tests again is seen as a separate run, so in case of failed layout tests the PulseAudio module would also be loaded and unloaded twice.
