Ah ok.... So you should look at what Pablo did because he is handling this case for code update, the idea is that he will put on the stack a kind of notifier so that you get aware when the m is not on the stack anymore.

This is exactly my usecase, i need to remove code that may be called by a method on the stack - and i know exactly which method. However my base hypothesis is that it is in an already running process (maybe a loop) and that part i cannot change. Is there an existing Pharo implementation of MethodWrappers ?
How can you remove a method if it may be called?
Stef
Lets say i have the following method:
m
^self m1
I have dynamically changed the code of m for a specific object o by the following:
m
self m2.
^self m1
m2 is behavior that is dynamically added to the object o.
If i want to revert the object o to its original behavior, that will change back m and remove m2, i must be sure that the changed m is not on the stack, else it could still call m2 that no longer exists.
Actually i tried Ben's suggestion, and it works. I just ask the process to run until the method i target is popped out of the stack and then i can remoev my code.
