This is correct. We can't have it rip the route out from under any
number of PCBs and other routes which may have it referenced.

No, the next time that route structure is used, the lack of an RTF_UP
flag on the route will be noted, and the reference will be dropped
before rtalloc() is called to find the new correct route. If you want
the references to be dropped sooner, either send more traffic or close
your connections more frequently.
