Comment (by jdemeyer):

 I'm collecting some "special cases" for doctests in
 [http://boxen.math.washington.edu/home/jdemeyer/doctest/] (maybe these
 should eventually become "meta-doctests").

 The doctesting framework seems to hang on
 {{{
 jdemeyer@sage:/release/merger/sage-5.1.beta5-12415$ ./sage -t
 /home/jdemeyer/doctest/sigdie.py
 Running doctests with ID 2012-06-26-14-12-55-fbefc7c4.
 Doctesting 1 file.
 }}}

 While the following gives an error inside the doctesting framework (this
 also used to fail before):
 {{{
 jdemeyer@sage:/release/merger/sage-5.1.beta5-12415$ ./sage -t
 /home/jdemeyer/doctest/keyboardinterrupt.py
 Running doctests with ID 2012-06-26-14-12-38-b70e54c4.
 Doctesting 1 file.
 sage -t /home/jdemeyer/doctest/keyboardinterrupt.py
 Traceback (most recent call last):
   File "/release/merger/sage-5.1.beta5-12415/local/lib/python2.7/site-
 packages/sage/doctest/reporting.py", line 146, in report
     ntests, runner = results
 TypeError: 'NoneType' object is not iterable

 }}}

 The following should report an error but doesn't:
 {{{

 /home/jdemeyer/doctest/sig_on.py

 ------------------------------------------------------------------------
 All tests passed!
 ------------------------------------------------------------------------

     cpu time: 0.1 seconds
     cumulative wall time: 1.1 seconds
 }}}
