The real fix for this is to add reference counts. That way we really know
when no one else has a copy of the pointer. Way back when I made the
initial patch for deleting interfaces, I added code so that we added and
deleted references, and only deleted the innards of an ifnet (and ifaddr) =
=20
when the count went to zero. Thus we should be able to avoid this whole
class of errors.

Take care,

Bill
