In r14119 poisoning regression tests were enabled. These stress read/write barriers. We got our first results [1] and there seems to be a problem in the finalizer thread, we have died in the PepTest of both Spec JBB versions [2] [3].

~~RVM-633~~ might have an effect on this issue.

This should have been fixed with the new Finalization processing code.

The previous code was unsafe in that it did not use the correct barriers when accessing the ready for finalize table. Closing to be reopened if the error shows up again.
