It affects (affected) piglit. Piglit runtime on i965 on Jenkins went from 9
minutes to 33, noticeably slowing down overall Jenkins runtimes.

It seems to be fixed now, presumably by Connor's patch that fixed the assertion
failure. Would be interesting to understand more what was going on.

I'll let Mark confirm and close the bug.
