The quake test comes from the SPEC OMP benchmarks. While I believe this
suite is available to anybody, I don't think it's free. I was given
the test by our benchmarking team, I'll have to ask them if this is
publicly available/if they know of any publicly available tests that can
reproduce the issue.

I'm working on that as we speak. I was trying to eliminate the
possibility that the vclear patches would help solve the problem,
before digging any deeper. I should have some more information on
exactly where it's getting hung up in a few hours.
