More info:

The imap conversation (taken from transferer side during rapid forking
failure mode) looks like this:

<1171989275<PROXY0 GETANNOTATION "user/bob" ("*") ("value.shared")
>1171989275>* ANNOTATION "user/bob" "/vendor/cmu/cyrus-imapd/server"
("value.shared" "master.<remaining domain removed>")
PROXY0 OK Completed

This is repeated many times per second, only the time stamp is
different. "PROXYO OK Completed" Seems like a positive response, but
perhaps the transferer expects a different response and tries again? I'm
currently trying to match this up the code.

Trace quoted below for reference,

Any clues would be great, thanks,
Shawn
