 But you probably have to take resumption into account -- a client may
restart sending requests from the point it stopped.  It may happen after a
link is restored somewhere on the way after a break, for example.  Though
I haven't checked if there's any timeout defined in the MOP spec or
imposed by specific MOP download clients -- perhaps there is.

 Mine tend to do that after I do `ifconfig <iface> down', which is what I
sometimes do.  I need to remember to restart mopd then.  Perhaps mopd
should monitor interfaces appearing and disappearing in general, taking
the restriction on the command line into account, of course.
