Just doing a bandwidth resignal, nothing else is changing. I see the 
same behavior with the ActiveRoute count, it drops to 0 for about 14 
seconds after the resignal, then pops back up to where it was before.

I don't have anything in the 9.3's to test, but 9.6S5 is definitely
doing the same thing. I also confirmed that the route changes in
rtsockmon are from routes pointing to LSPs which just resignaled, which
stops as soon as the install-nexthop config goes away. I'm not
particularly interested in going to a full cos next-hop-map setup, but
this is definitely broken as-is. :)
