<pre>It definitely seems to be some kind of race - adding usleep(1000) in the test
inbetween glMapBufferRange and the p[i] access effectively hides the problem.
It also works fine on Haswell - I've run it for a few hours with no failures.
INTEL_DEBUG=sync doesn't help. always_flush_batch=true seems to make it fail a
little more often...it at minimum doesn't help...</pre>
