   The free program Maxima computes this integral  (a mess) in 2.68 seconds   
   on my 7 year old computer.  Evaluating it to a 40-digit precison number   
   gives appx   
   1.138911319801756364346365520822589787737 plus an imaginary part that   
   seems to be about one unit in the last place of the computation...   
   which can be recomputed to a higher precision to check.   
      
   This agrees with the NIntegrate from Mathematica version 9   
   to about 13 digits.
