Hmm, acually, I might have killed it when it was busylooping...
But with sig15 of course. Now, after your change, I found it
busylooping.  Here goes the trace:

Yes, the difference is that on this machine there is a bunch of
addresses in SELFADDRS (I configured it "ETRN cluster ready" when I
evaluated Intel TCP redirector).  Looks like it is looping in
stashmyaddresses...

P.S. I am leaving till Thursday, won't be able to read mail.
P.P.S Pity that you where not at USENIX conference in San Diego.
  If you are curious how it went, I have pictures here:
