Sounds familiar. Looping through PROGRAM() just for listing the stack sounds not wise since we have ASTACKINFO. But here it's just about who calls a method. I guess it might not be of much influence - if, the use of ACCESS_ might be the bigger problem.
I doubt the idea of figuring out who calls ACCESS_ method at all. I would check for action/write by a different property, but then, it's not my solution.
