Thank's a lot Andrew and Dennis.

Ok. I added a STOP message to my protocol, so now the client
shuts down the socket first (when it has read the STOP), and
then it seems to work much better. What I did, in case the
client gets behind, was this in my handle method: I send a STOP
message repeatedly with a delay. When the client gets the first
one, it will close the socket, and I will get an exception the
next time I try to send. This seems to work well, without
(I hope) introducing any new potential problems.

...
delay = 1
print "No more data to serve. Send STOP message."
print "Waiting for client to close socket."
while 1:
     try:
         self.request.send("STOP\n")
         time.sleep(delay)
         print '.'
     finally:
         sys.exit()
