--- Comment #1 from David Smith <dsmith at redhat dot com> ---
Fixed in commit d3be3bf (tested on s390x rhel7).
We were checking for read access to the task structure, but just because we can
safely read the task structure doesn't mean we can safely write to the task
structure. Fixed by no longer trying to lock the task structure.
