--- Comment #1 from Jeffrey A. Law <law at redhat dot com> ---
Thanks Bill. This test might have been compromised by the recent threading
changes. Before the changes, VRP1 picks up a few FSM/backward jump threads,
which in turn hide an old style jump thread. Leaving just enough tidbits for
DOM2 to find and optimize.
After my change, VRP1 isn't picking up any FSM/backward threads (as expected),
but it picks up the jump thread that previously was missed until DOM2.
I'm still looking at a couple loose ends, but that's how things look right now.
