Following up on what Rob said, here's what the bottom of timing.log shows:

 1.0x reverse-complement
 1.2x mandelbrot
 1.4x k-nucleotide
 1.4x nbody
 1.5x fasta
 1.7x meteor
 2.0x spectral-norm
 2.1x fannkuch
      (better array bounds checks would get to 1.5x)
 5.6x binary-tree
      (comparing malloc+free against garbage collector)
10.5x regex-dna
      (different algorithms; Go has better worst case)
14.8x pidigits
      (different bignum packages)
 0.7x chameneos
      (different thread libraries)
 1.0x threadring
      (different thread libraries)

Only the first eight are close to fair comparisons, and Go is doing
reasonably well.  I don't believe it would take much to get those to 1.2x.
