Before I showed you the results from my custom scripts. To exclude any 
unnecessary influence, I let it run again: on the loopback device and 
just with broping.bro:

src/bro -i lo -C aux/broccoli/test/broping.bro

The results:
noloop     13.26
default    89.68
patch      77.14
pcap       32.7
pcap+patch 50.2
1.5        87.45

The regression of the patch is visible with the default version of 
libpcap, but not with Phil Wood's. Not sure wether I had a calculation 
error there before (dnt have the resutls from the first run anymore).
