Ideally, making a compartment a Debugger's debuggee should have no impact on its performance, beyond that imposed by running the Debugger's user's code. However, as shown in the plots attached to bug 914429, making a compartment a Debugger debuggee slows down execution in that compartment quite a bit, even if we're not messing with the debuggee at all. This is a meta-bug for all efforts to ameliorate that effect.
