Thanks, it indeed seems to fix the issue:

  (running under qemu-kvm -smp 2 ...)
  $ sysctl hw.ncpu
  hw.ncpu: 2
  $ for i in `seq 1 10`; do time ./test-once >/dev/null; done
          8.73 real         4.50 user        12.15 sys
          9.59 real         4.35 user        13.50 sys
          9.18 real         4.50 user        12.80 sys
          8.92 real         4.29 user        12.66 sys
          8.81 real         4.53 user        12.26 sys
          8.80 real         4.45 user        12.33 sys
          8.72 real         4.23 user        12.39 sys
          9.11 real         4.40 user        12.77 sys
          8.86 real         4.36 user        12.43 sys
          9.10 real         4.49 user        12.65 sys
