Yep, sound like it.
What I just tried ( and what partially works, at least for my purpose) is to 
have a perspective_disconnect method in the perspective class which just 
free's up the ressources I want to get rid of. certainly the connection still 
hangs around until I close the client. I my case droping the database 
connection which is no longer in use is more of a concern, so that works for 
me. (each client opens 2 database connections at startup - one is solely for 
login and gui definitions and has no password, the second is started after 
login. Therefor I don't need the first connection anymore. But I need to 
close the db connection since this server is intended to serve possibly up to 
500 clients at a time, which would be 500 useless db connections)
