route not being deleted from wm0

["Steven M. Bellovin" <smb%cs.columbia.edu@localhost>]

I often move my laptop between wired (wm0) and wireless (wpi0)
connections to the same subnet.  Going from wpi0 to wm0 access works
fine.  However, when I go the other way, there's a subnet route that
hasn't been deleted.  Is there some bug in the wm0 driver or perhaps
in one of the pieces it depends on that wpi0 doesn't use?  I believe
hubertf has run into the same thing; see the comment about 'route flush'
