You should look at the weak array object support.

Take a look at StandardFileStream class category registery
see the register:, registry, unregister:

Also see on the finalize instance side category
actAsExecutor if you are making copies of your object
and finalize which is what your object gets when finalized.
This *might* get called twice...
Plus see unregister & register.

In your finalize routine I'd suspect you would close/delete the file in  
question.

Note that finalization occurs later where later can be milliseconds to  
minutes base how where the object dies, young space, or old space.
