Comment (by jhpalmieri):

 I have no idea what's going on, but to follow up on David's comment: on an
 OS X 10.8 machine, if I run `sage -t rings/big_oh.py tests/interrupt.pyx`,
 I get an error at line 744. If I make ''either'' of the following two
 changes, the error goes away:
 {{{

 For the second one, I still get the error if I keep line 744,
 {{{
 sage: from sage.tests.interrupt import *
 }}}
 but remove the actual doctest. Does this have any significance for anyone?
