ITS#9354 cleanup watcher

Browse source 
After initial contact, don't exit if a server goes down.
Also, don't wait forever for responses, use a timeout and
mention when a timeout occurs.
Simplify csn/sid handling, we know the max we expect so just
allocate the space in advance and keep a fixed sid to slot
mapping.
