Ah, thanks Bill for the correction - my mistake.

So that probably makes it a lot simpler. So if I wanted a command line 
like this:
gaps.py --duration 2 --host 127.0.0.1 --port 6544

or
gaps.py -d 2 -n 127.0.0.1 -p 6544

this patch might do the trick?

Seems to work for me anyway (sample size = 1).
