My usage works generally like:

start server
start client
connect client to server
start game
client times out
reconnect client to server
while (1)
  do unit actions for the turn
  buy improvements
  (Sometimes) kill client
  start & connect client
  finish turn
repeat

I kill the client occasionally because otherwise it has a nasty tendency 
to keep taking memory until I run out of swap, at which point I need to 
kill it anyway to get anything done.  I believe that when I finished the 
two turns preceding the savegame that I hadn't done this, and that 
instead during the 'finish turn' process, after I had finished one turn 
and the message window for the next year had popped up but before I had 
the chance to perform any actions in the new year, the client timed out 
and disconnected.
