this is a known corner case and will always be there.  it's why the kernel 
guys have deprecated the hotplug exec mechanism in favor of netlink sockets.  
the only real solution is a daemon + netlink.  neither of which are desirable 
in mdev.  everything else is a workaround.  feel free to contribute a 
mdevd ;).  that plus init/other daemons provided by busybox are good examples 
of how PIE can be a very very good thing.
