has two problems:

 * not all LANs might be shaped so there may not be a delay-agent running
   to receive and acknowledge the RESET event, leading to a hang

 * we might wind up resetting a delay node more than once (once for each
   lan it is responsible for); probably not harmful, but might lead to
   again not sending a completion event and a hang.

As long as I can reset the one LAN I care about, or rather all its involved
delay nodes, I should be fine.
