commit 3fb24a3676d8a6e35bd9e5d1e30ad95fc5281a32
Author: David Smith <dsmith@redhat.com>
Date:   Fri Aug 17 13:31:24 2012 -0500

    Fixed PR14463 by changing error handling of utrace_control().
    
    * runtime/stp_utrace.c (utrace_barrier): Add a 'might_sleep()' call since
      it calls schedule_timeout_interruptible(), which sleeps.
    * runtime/linux/task_finder2.c (__stp_utrace_attach): Ignore
      EINPROGRESS errors from utrace_control() when passed UTRACE_STOP, since
      that just means the task hasn't stopped yet.
    * runtime/linux/task_finder.c (__stp_utrace_attach_flags): Ditto.
