<pre>I've done a bunch of poking at this including running it on Windows (where it
doesn't hang) and getting an aub capture. There's nothing obvious that we're
really doing differently. :-( I'm guessing there's some L3$ chicken bit we're
missing somewhere.
I also experimented with reworking the test to use a fragment shader instead of
a compute shader and was able to reproduce the hang with FS as well. This
eliminates any it's some GPGPU workaround we're missing.</pre>
