that's memory corruption - which robust futexes do not (and cannot)
solve. Robustness is mostly about handling sudden death (e.g. which is
due to oom, or is due to a user killing the task, or due to the
application crashing in some non-memory-corrupting way), but it cannot
handle all possible failure modes.
