Normally URP program calls socket\_open and keep open state.  
Sometimes later program is stopped by user in polyscope. and restarted.  
In that case, we could not call socket\_close() explicitly when stopping.  
Does URControl process call socket\_close() internally?

When a program using sockets is stopped, all remaining open sockets are closed.  
However it is good practice, to use `socket_close()` yourself to ensure proper housekeeping.
