Wow, this stuff is absolutely awesome! It will definitely be very helpful to reproduce certain classes of bugs which have already required some stuff like tcploop.c! So please add this to contrib/ (eg: contrib/plug_qdisc or whatever you like) with 3-5 lines of README to help a developer quickly spot how to call it. No need for details, those who can't figure how to build it don't need it anyway. Thanks, Willy
