No, I didn't parallelize.

I should add that the program has two steps - first to create the 
polynomials, and then to multiply them.  To create the polynomials, I 
could have used GiNaC, but I didn't have to do anything more complicated 
algebraically than multiply by x.  So I used GMP directly for that part. 
  According to the documentation, GiNaC uses GMP for its floating point 
arithmetic.  And GMP seems to allow powers of ten way larger than plus 
or minus 10000.
