--- Comment #1 from David Smith <dsmith at redhat dot com> ---
Fixed in commit 386e80c.

The stap_task_finder_post_init() function was written to interrupt tasks that
were sleeping. In this case, the task is running. The task_finder2 code was
updated to only interrupt tasks that are in the TASK_INTERRUPTIBLE state.
