router cycling (.50-s6)

[Eugene Crosser <crosser@online.ru>]

Matti,

Today I noticed a router process that was cycling since 15 Sep and did not
die on simple kill (15).

root 20223     1 42   Sep 15 ?       25889:11 router -dkn 8

Before killing it with -9, I attached to it with gdb and here is the
backtrace.
