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.
