Interesting.  Based on exactly your code (all I did was change the
input file name [and remove the hyphen from Bhagavad-Gita :-]), I'm
getting:

		   user     system      total        real
   primes      3.660000   0.010000   3.670000 (  3.669972)
   unpack      2.800000   0.010000   2.810000 (  2.808476)
   primes      3.230000   0.000000   3.230000 (  3.227572)
   unpack      2.720000   0.000000   2.720000 (  2.725597)

I then thought maybe taking the asc2prime assignment out of the method
would speed it up, but:

		   user     system      total        real
   primes      3.630000   0.030000   3.660000 (  3.654865)
   unpack      2.540000   0.010000   2.550000 (  2.652403)
   primes      3.280000   0.000000   3.280000 (  3.293865)
   unpack      2.490000   0.000000   2.490000 (  2.486077)

I guess it's OS-related -- ??  Or Ruby version-related?
