I'm assuming you'll do this in advance of any patch from me? I was

debug output was too verbose.
Let me know and I'll help if I can,

I was going to grind through it unless/until you sent a patch.

You mean logging on the client or server side? I'm currently bisecting
client. I'm happy to add some extra prints there if you point me in the
direction of the code paths of interest.
