Following up ....  I found out that the deadlock problem is avoided
in the current hotplug net.agent script.  It uses ps to check
running instances of ifup and refrains from running ifup a second
time for the same interface.

    if ps -C ifup ho args | grep -q "$IFUPARG"; then
        debug_mesg "ifup-ing now"
