Sometimes Can't Recover From Purged Callbacks

[GoogleCodeExporter]

Flaky Internet connections can't recover after purged callbacks.

---------------------------------------------------------------------

Hi.

I'm trying to update from the code that was in your trancheproject repo 
(which was working fine, if a bit slowly), to the download from google 
code.  I'm getting the exceptions below, reproducibly.

I'm using an older tranche.conf (attached), because the distro from google 
code doesn't seem to have one.  I want to let users change this out for 
their own, if they're using their own Tranche network.  This may be part of 
the problem.

I'm going to roll back to the older code for the time being.

Any help you could offer would be most appreciated.

Difficult to replicate. Made changes that alleviate the problem somewhat.
