I am not quite sure I understand what is going on ...

In general for Eclipse stuff:
1- the constructor does *no* work
2- there is a seperate init method that is called (often with some kind 
of DialogSettings or IMemento to store configuration info between runs)
3- there is a method that does some work
4- and a dispose() method to clean up

You can see this happen for the Eclipse "Views" (it does steps 1 - 5). 
The IOp does steps 1 and 3 if I remember correctly... only a single 
instance of the IOp would be constructed, and it would be called with 
different parameters each time the user asks.
