Log:
  For kinfo_proc in kp->ki_siglist, return the set of the signals pending
  in the process queue when gathering information for the process, and set
  of signals pending for the thread, when gathering information for the
  thread. Previously, the sysctl returned a union of the process and some
  arbitrary thread pending set for the process, and union of the process
  and the thread pending set for the thread.
