Thanks, yep, including () optimisation :-)

Dear volunteer/victim: Last time I looked,
  ping -f -s5000 victimip &
  ping -f -s10000 victimip &
  ping -f -s15000 victimip &
  ping -f -s20000 victimip &
  ping -f -s25000 victimip &
  ping -f -s30000 victimip &
  ping -f -s35000 victimip &
while running something buffer intensive (bonnie etc.)
tended to do a fair job of exercizing the machine's
powers of memory fragmentation / defragmentation;
reassembly of IP fragments allocates memory GFP_ATOMIC.
