----------------------+-----------------------------------------------------
 Reporter:  was       |       Owner:  burcin  
     Type:  defect    |      Status:  new     
 Priority:  blocker   |   Milestone:  sage-4.0
Component:  calculus  |    Keywords:          
----------------------+-----------------------------------------------------

Comment(by was):

 TODO: This doctest in infinity.py was commented out.  When uncommented we
 get a total hang:
 {{{
             sage: bool(SR(oo) == sympy.oo)
 }}}

 This is what we get:
 {{{
 sage:             sage: bool(SR(oo) == sympy.oo)
 terminate called after throwing an instance of 'std::runtime_error'
   what():  indeterminate expression: Infinity - Infinity encountered.


 ^V^C^C^C^C^C^C^Z
 }}}

 I'm uncomenting this in my referee patch.
