Consider me also on the hook for that.

Getting the tests hooked back up is high on my list, also Travis.

Are we melting two CPUs with xtest at this point, or are there still

test list up, do multiple piglit-run.pys in parallel, and merge results
later.  I think piglit has support for doing that.
