I was using routed over a UDP tunnel
(/usr/share/examples/netgraph/udp.tunnel) to distribute
routing information over some DSL lines. This stopped
working when I upgraded one of the routers to FreeBSD-6.
I never reported it, feeling that the setup(PPPoE + netgraph
UDP tunnel + routed) to reproduce it, is somehow complicated.
It seems that after Maxime's changes, the deadlock I was
seeing is gone. Testing a similar setup, seems to work,
as it did in the pre-FBSD-6 days.
