Since rsync is keeping the socket busy during the building of the list
(it is trasmitting it during that time), I guess the sorting/cleaning of
the list is taking enough time that the socket timeouted out on you.
I'm glad that the setting of SO_KEEPALIVE did something to help fix your
problem, but I'm having a hard time seeing why:  the code should set
that for all daemon socket connections (excluding only daemon-over-ssh).
Are you using the --timeout=N option to rsync (which is an internal-to-
rsync timeout value, unrelated to the TCP timeout).
