i am investigating the problem.

First, the "next" branch seems to behave marginally better in
terms of robustness, but it still shows entries being inserted
exactly every 100 ms which looks like the effect of some timeout
(tipfw/ipfw and ./kipfw communicate through a tcp socket,
tcpdump shows that the ack is delayed by 100ms which slows
down everything.

Need to investigate which tcp sockoptions remove this delay..

cheers
