Numbers when running on Linux on a laptop with 2 cores + hyperthreading.

RUNNING UNITTESTS:
  fork:
    real    0m50.687s
    user    0m9.213s
    sys     0m4.012s

  fork+exec:
    real    1m9.062s
    user    0m48.579s
    sys     0m6.648s

  forkserver:
    real    0m50.702s
    user    0m4.140s        # excluding descendants
    sys     0m0.708s        # excluding descendants

LATENCY:
  fork:       0.0071 secs/proc
  fork+exec:  0.0622 secs/proc
  forkserver: 0.0035 secs/proc

Still 4 times the cpu time and 10 times the latency.  But the latency is far lower than in the VM.
