the fact that i am using 2.2 is stated in the subject line. i did neglect to 
put it explicitly put it in the message (sorry).  it is, however, also 
diff/patch file.

I also do not think that nuking valid routes in the cache will produce any
major issues, other than slowing things down for a few seconds.  the cache
is just the cache, not the real route table. and yes, it pretty much 
guarantees the route cache will be purged, therefore avoiding a reboot and
avoiding a quickly repeated overflow...

and yes, having the source makes things much easier. :)
