sync_client stalls the rest of cyrus while 'no route to host'

[Paul Dekkers]

Hi,

I don't know if this is a known issue: as soon as I enable replication
and the sync_client gets a "No route to host" from the replica, the rest
of the cyrus startup seems to stall: no imap, no lmtp... just because a
replica is unreachable. (In this case because iptables was to
restrictive on the replica ;-))

It takes quite long, not sure if the server will ever respond...

P.S. I tried this in a test-enviroment running RHEL4 with
cyrus-imapd-2.3.7-3 from Simon.
