I think there is a bug in that documentation - the paragraph:

  Note that if an otherwise unhandled SystemError is raised, this
  function will not return 1, but exit the process, as long as
  Py_InspectFlag is not set.

Looks like it should refer to SystemExit, not SystemError.  If you check 
out pythonrun.c in handle_system_exit, you will note the behaviour 
described above is exactly what is implemented for SystemExit.
