@damian-sawicki: yes, but once such memory errors DO occur, I think your
system is basically compromised; you don't know when it will crash (*)
and you don't know what else gets corrupted before the lock-up (why not
filesystem errors, security etc?). That's why I would cut this at the
root.

(*) In practice, of course, the system seems to actually crash when
under heavy swapping the erroneous block gets used (possibly when the
page is swapped back into memory?) But this is like overclocking, you
never know what parts of the system might break.

We need to figure out why there aren't more people affected by this
issue and how to get developers involved. Perhaps we should mark this as
a security problem (because memory errors usually DO lead to security
problems, even if writing an exploit could be hard)
