At most it will only keep the last machines scanned when outputting
via the pktkludge output. It's supposed to be a real time component to
give you something to alert on and then go look at NetFlow-esque data
from that around that alert timerange to find out what was actually
being scanned.

I'll be the first to admit configuring it's a PITA but it's good at
being consistent on memory usage.  It also suffers from it was shoved
into the same old output systems that everything else uses..

I think it also has way too many end user knobs exposed by default so
the command line configuration really sucks.
