[Olsr-dev] unusable OSX routing table

[math]

OSX writes entries into the routing table that aren't deleted after  
exiting and lead to an unusable system at runtime.
It seems as if the UGH routes don't aren't deleted anymore, but the UC  
and UHLW routes work fine.
(why are the UHLW routes needed anyway?)

How can this be fixed?
