It looks like commit da35c58 for bug #14463 fixed this problem also. That
commit changed the order of events that happen when a clone occurs.
====
Improve PR14463 by avoiding sleeping in the clone handler.
* runtime/linux/task_finder2.c (__stp_tf_alloc_task_work): Change
parameter to a void pointer.
(__stp_tf_clone_worker): New function.
(__stp_utrace_task_finder_report_clone): Uses stp_task_work_add() to
call __stp_tf_clone_worker() when we can safely sleep.
