I think so. It shouldn't require a huge learning curve since it ought to be a matter of wiring up existing code to run at times when it does not currently run. ie, I don't think there's a lot of new code to write to make this work.
The biggest issue with these warnings at -O0 (as others have mentioned) is going to be the potential for compile-time slowdowns. \Jeff
