We've had a number of reports of the "PresArena: poison overwritten" assertion (bug 772725, bug 775045) that seem likely to be the result of bad hardware rather than bad software. Given that bad hardware seems likely to result in things like single bit errors, and bad software seems likely to result in entire words being overwritten, we should make this abort print more information so that we can distinguish the two cases.
