[Seaside] Where can I put "clean up" code

[Michael]

Hi
I would like to retrieve my data from a RequestBroker. I have a subclass 
of WAComponent
(For example WATest).

In WATest>>initialize I have this code: client := RequestBroker 
newStstTcpAtPort: 4243.
In WATest>>renderContentOn I load the current data every time the method 
gets called.

No I would like to know where I should place the "client close" 
statement. This statement
should be executed when Seaside abandons the instance of WATest.

Cheers, mike
