--- Comment #9 from David Smith <dsmith at redhat dot com> ---
Fixed in commit d9edc5f (which is different than the attached patch). With this
patch, a module without debug prints works fine.

With debug prints (-DDEBUG_TASK_FINDER=9 -DSTP_TF_DEBUG=9), we still get an
occasional delay when exiting with this patch. An occasional delay when using
debug prints is certainly better than a crash. The delay doesn't appear to be
related to task_finder/utrace shutdown, for some reason there is a delay in
calling stap_stop_task_finder(). We may have to look into this further in the
future.
