I was speaking in error - I did not see that the snapshots had version
numbers, so I thought 2.1.3 was the most current with a version number. 
Per my previous message this morning, I've corrected that assumption.

Yes, but coldsync.c performs a select() directly on pconn->fd (in
forward_netsync).  It's probably safe to assume that will always be OK
for a network connection, but it's performed on the local pconn->fd as
well.

Of course, the current API of io_select doesn't support what
forward_netsync attempts to do with select(), which is a problem :-/
