Sorry, I didn't notice this in the previous version. on_dispatch looks like an internal property and I don't see how we can stop a process with ptrace when on_dispatch is set to a non-zero value. I am not sure that we need to expose it to user-space.
Other than that, the patch looks good to me.
Thanks, Andrei
