Ok, thanks for information. Am still however wondering what i can pass
to doneWith and what not. Do you mean i can pass any corba object am not using anymore, 
except those have connect() in their interface? Also, can i call any of the doneWith(x) methods or
only the one present on object y where x was create by a call a getter of y
