<pre>Hello,
"bufferstorage-persistent read client-storage" piglit test fails intermittently
with a very low fail-to-pass ratio in Mesa master.
When running "bufferstorage-persistent read client-storage" piglit test during
20/30 minutes in an infinite loop on a Haswell laptop, I got the following
error:
$ while (true); do (bin/bufferstorage-persistent read client-storage -auto -fbo
| grep -v pass); done
