I think you can safely just remove the realserver, and still existing 
connections will keep working until they terminate.

Setting weight to 0 still makes sense when you want to temporarily take 
a realserver out of service, as the concurrent connection count for least-
connection scheduling is kept intact that way (and the connection count 
can still be monitored while the weight is 0).
