This bug seems to have become a catch-all for a smattering of varying kinds of failures in a variety of unrelated sub-tests, with this test file the only the only common aspect.  When reporting via data that will go away, please, at least, include the sub-test name, error message, and backtrace -- so that I can some hope of figuring what is going on.

Thanks,
Robert

This has been observed to fail once on Linux X64. It looks to be intermittent, but requires more attention since it is a tier 1 test.
