2's the only case I've ever used for MAKEALL, I'll add the other cases
as you suggest.

I didn't trap 0 because I wasn't aware of a quick way to only call
print_stats once when ctrl-c was pressed (eg trapping 0 and 2 would
result in 2 print_stats calls with the current code).  Let me know if
there's a standard way to workaround this.

Best,
